dissertation and hypothesis difference

The Real Differences Between Thesis and Hypothesis (With table)

A thesis and a hypothesis are two very different things, but they are often confused with one another. In this blog post, we will explain the differences between these two terms, and help you understand when to use which one in a research project.

As a whole, the main difference between a thesis and a hypothesis is that a thesis is an assertion that can be proven or disproven, while a hypothesis is a statement that can be tested by scientific research. 

We probably need to expand a bit on this topic to make things clearer for you, let’s start with definitions and examples.

Definitions

As always, let’s start with the definition of each term before going further.

A thesis is a statement or theory that is put forward as a premise to be maintained or proved. A thesis statement is usually one sentence, and it states your position on the topic at hand.

The best way to understand the slight difference between those terms, is to give you an example for each of them.

If you are writing a paper about the effects of climate change on the environment, your thesis might be “Climate change is causing irreparable damage to our planet, and we must take action to prevent further damage”.

If your hypothesis is correct, then further research should be able to confirm it. However, if your hypothesis is incorrect, research will disprove it. Either way, a hypothesis is an important part of the scientific process.

The word “hypothesis” comes from the Greek words “hupo,” meaning “under”, and “thesis” that we just explained.

Argumentation vs idea

A thesis is usually the result of extensive research and contemplation, and seeks to prove a point or theory.

A hypothesis is only a statement that need to be tested by observation or experimentation.

5 mains differences between thesis and hypothesis

Thesis and hypothesis are different in several ways, here are the 5 keys differences between those terms:

So, in short, a thesis is an argument, while a hypothesis is a prediction. A thesis is more detailed and longer than a hypothesis, and it is based on research. Finally, a thesis must be proven, while a hypothesis does not need to be proven.

Is there a difference between a thesis and a claim?

Is a hypothesis a prediction.

No, a hypothesis is not a prediction. A prediction is a statement about what you think will happen in the future, whereas a hypothesis is a statement about what you think is causing a particular phenomenon.

What’s the difference between thesis and dissertation?

A thesis is usually shorter and more focused than a dissertation, and it is typically achieved in order to earn a bachelor’s degree. A dissertation is usually longer and more comprehensive, and it is typically completed in order to earn a master’s or doctorate degree.

B oth the hypothesis statement and the thesis statement answer the research question of the study.  When the statement is one that can be proved or disproved, it is an hypothesis statement.  If, instead, the statement specifically shows the intentions/objectives/position of the researcher, it is a thesis statement.

A hypothesis is a statement that can be proved or disproved.  It is typically used in quantitative research and predicts the relationship between variables.

A thesis statement is a short, direct sentence that summarizes the main point or claim of an essay or research paper. It is seen in quantitative, qualitative, and mixed methods research.  A thesis statement is developed, supported, and explained in the body of the essay or research report by means of examples and evidence.

Every research study should contain a concise and well-written thesis statement. If the intent of the study is to prove/disprove something, that research report will also contain an hypothesis statement.

Let’s say you are interested in the conflict in Darfur, and you conclude that the issues you wish to address include the nature, causes, and effects of the conflict, and the international response. While you could address the issue of international response first, it makes the most sense to start with a description of the conflict, followed by an exploration of the causes, effects, and then to discuss the international response and what more could/should be done.

This hypothetical example may lead to the following title, introduction, and statement of questions:

Conflict in Darfur: Causes, Consequences, and International Response       This paper examines the conflict in Darfur, Sudan. It is organized around the following questions: (1) What is the nature of the conflict in Darfur? (2) What are the causes and effects of the conflict? (3) What has the international community done to address it, and what more could/should it do?

Following the section that presents your questions and background, you will offer a set of responses/answers/(hypo)theses. They should follow the order of the questions. This might look something like this, “The paper argues/contends/ maintains/seeks to develop the position that...etc.” The most important thing you can do in this section is to present as clearly as possible your best thinking on the subject matter guided by course material and research. As you proceed through the research process, your thinking about the issues/questions will become more nuanced, complex, and refined. The statement of your theses will reflect this as you move forward in the research process.

So, looking to our hypothetical example on Darfur:

The current conflict in Darfur goes back more than a decade and consists of fighting between government-supported troops and residents of Darfur. The causes of the conflict include x, y, and z. The effects of the conflict have been a, b, and c. The international community has done 0, and it should do 1, 2, and 3.

Once you have setup your thesis you will be ready to begin amassing supporting evidence for you claims. This is a very important part of the research paper, as you will provide the substance to defend your thesis.

Both the hypothesis statement and the thesis statement answer a research question. 

• A hypothesis is a statement that can be proved or disproved. It is typically used in quantitative research and predicts the relationship between variables.  
• A thesis statement is a short, direct sentence that summarizes the main point or claim of an essay or research paper. It is seen in quantitative, qualitative, and mixed methods research. A thesis statement is developed, supported, and explained in the body of the essay or research report by means of examples and evidence.

Every research study should contain a concise and well-written thesis statement. If the intent of the study is to prove/disprove something, that research report will also contain a hypothesis statement.

NOTE: In some disciplines, the hypothesis is referred to as a thesis statement! This is not accurate but within those disciplines it is understood that "a short, direct sentence that summarizes the main point" will be included.

Difference Between Thesis and Hypothesis

Main difference –  thesis vs hypothesis                           .

Thesis and hypothesis are two common terms that are often found in research studies. Hypothesis is a logical proposition that is based on existing knowledge that serves as the starting point of an investigation. A thesis is a statement that is put forward as a premise to be maintained or proved. The main difference between thesis and hypothesis is that thesis is found in all research studies whereas a hypothesis is mainly found in experimental quantitative research studies.

This article explains,

1. What is a Thesis?      – Definition, Features, Function

2. What is a Hypothesis?      – Definition, Features, Function

What is a Thesis

The word thesis has two meanings in a research study. Thesis can either refer to a dissertation or a thesis statement. Thesis or dissertation is the long essay or document that consists of the research study.  Thesis can also refer to a theory or statement that is used as a premise to be maintained or proved.

The thesis statement in a research article is a sentence found at the beginning of the paper that presents the main argument of the paper. The rest of the document will gather, organize and present evidence to support this argument. The thesis statement will basically present the topic of the paper and indicate what position the researcher is going to take in relation to this topic. A thesis statement can generally be found at the end of the first paragraph (introductory paragraph) of the paper.

What is a Hypothesis

A hypothesis is a logical assumption based on available evidence. Hypothesis is defined as “a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation” in the Oxford dictionary and as “an idea or theory that is not proven but that leads to further study or discussion” in the Merriam-Webster dictionary. In simple words, it is an educated guess that is not proven with concrete scientific evidence. Once it is scientifically tested and proven, it becomes a theory. However, it is important to note that a hypothesis can be accurate or inaccurate.

Hypotheses are mostly used in experiments and research studies. However, hypotheses are not used in every research study. They are mostly used in quantitative research studies  that deal with experiments. Hypotheses are often used to test a specific model or theory . They can be used only when the researcher has sufficient knowledge about the subject since hypothesis are always based on the existing knowledge. Once the hypothesis is built, the researcher can find and analyze data and use them to prove or disprove the hypothesis.

Thesis: A thesis is a “statement or theory that is put forward as a premise to be maintained or proved” or a “long essay or dissertation involving personal research, written by a candidate for a university degree” (Oxford dictionary).

Hypothesis: A hypothesis is “a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation” (Oxford dictionary).

Thesis: Thesis statement can be found in all research papers.

Hypothesis: Hypotheses are usually found in experimental quantitative research studies.

Thesis: Thesis statement may explain the hypothesis and how the researcher intends to support it.

Hypothesis: Hypothesis is an educated guess based on the existing knowledge.

What Is A Research (Scientific) Hypothesis? A plain-language explainer + examples

By:  Derek Jansen (MBA)  | Reviewed By: Dr Eunice Rautenbach | June 2020

If you’re new to the world of research, or it’s your first time writing a dissertation or thesis, you’re probably noticing that the words “research hypothesis” and “scientific hypothesis” are used quite a bit, and you’re wondering what they mean in a research context .

“Hypothesis” is one of those words that people use loosely, thinking they understand what it means. However, it has a very specific meaning within academic research. So, it’s important to understand the exact meaning before you start hypothesizing. 

Research Hypothesis 101

• What is a hypothesis ?
• What is a research hypothesis (scientific hypothesis)?
• Requirements for a research hypothesis
• Definition of a research hypothesis
• The null hypothesis

What is a hypothesis?

Let’s start with the general definition of a hypothesis (not a research hypothesis or scientific hypothesis), according to the Cambridge Dictionary:

Hypothesis: an idea or explanation for something that is based on known facts but has not yet been proved.

In other words, it’s a statement that provides an explanation for why or how something works, based on facts (or some reasonable assumptions), but that has not yet been specifically tested . For example, a hypothesis might look something like this:

Hypothesis: sleep impacts academic performance.

This statement predicts that academic performance will be influenced by the amount and/or quality of sleep a student engages in – sounds reasonable, right? It’s based on reasonable assumptions , underpinned by what we currently know about sleep and health (from the existing literature). So, loosely speaking, we could call it a hypothesis, at least by the dictionary definition.

But that’s not good enough…

Unfortunately, that’s not quite sophisticated enough to describe a research hypothesis (also sometimes called a scientific hypothesis), and it wouldn’t be acceptable in a dissertation, thesis or research paper . In the world of academic research, a statement needs a few more criteria to constitute a true research hypothesis .

What is a research hypothesis?

A research hypothesis (also called a scientific hypothesis) is a statement about the expected outcome of a study (for example, a dissertation or thesis). To constitute a quality hypothesis, the statement needs to have three attributes – specificity , clarity and testability .

Let’s take a look at these more closely.

Need a helping hand?

Hypothesis Essential #1: Specificity & Clarity

A good research hypothesis needs to be extremely clear and articulate about both what’ s being assessed (who or what variables are involved ) and the expected outcome (for example, a difference between groups, a relationship between variables, etc.).

Let’s stick with our sleepy students example and look at how this statement could be more specific and clear.

Hypothesis: Students who sleep at least 8 hours per night will, on average, achieve higher grades in standardised tests than students who sleep less than 8 hours a night.

As you can see, the statement is very specific as it identifies the variables involved (sleep hours and test grades), the parties involved (two groups of students), as well as the predicted relationship type (a positive relationship). There’s no ambiguity or uncertainty about who or what is involved in the statement, and the expected outcome is clear.

Contrast that to the original hypothesis we looked at – “Sleep impacts academic performance” – and you can see the difference. “Sleep” and “academic performance” are both comparatively vague , and there’s no indication of what the expected relationship direction is (more sleep or less sleep). As you can see, specificity and clarity are key.

Hypothesis Essential #2: Testability (Provability)

A statement must be testable to qualify as a research hypothesis. In other words, there needs to be a way to prove (or disprove) the statement. If it’s not testable, it’s not a hypothesis – simple as that.

For example, consider the hypothesis we mentioned earlier:

Hypothesis: Students who sleep at least 8 hours per night will, on average, achieve higher grades in standardised tests than students who sleep less than 8 hours a night.  

We could test this statement by undertaking a quantitative study involving two groups of students, one that gets 8 or more hours of sleep per night for a fixed period, and one that gets less. We could then compare the standardised test results for both groups to see if there’s a statistically significant difference. 

Again, if you compare this to the original hypothesis we looked at – “Sleep impacts academic performance” – you can see that it would be quite difficult to test that statement, primarily because it isn’t specific enough. How much sleep? By who? What type of academic performance?

So, remember the mantra – if you can’t test it, it’s not a hypothesis 🙂

Defining A Research Hypothesis

You’re still with us? Great! Let’s recap and pin down a clear definition of a hypothesis.

A research hypothesis (or scientific hypothesis) is a statement about an expected relationship between variables, or explanation of an occurrence, that is clear, specific and testable.

So, when you write up hypotheses for your dissertation or thesis, make sure that they meet all these criteria. If you do, you’ll not only have rock-solid hypotheses but you’ll also ensure a clear focus for your entire research project.

What about the null hypothesis?

You may have also heard the terms null hypothesis , alternative hypothesis, or H-zero thrown around. At a simple level, the null hypothesis is the counter-proposal to the original hypothesis.

For example, if the hypothesis predicts that there is a relationship between two variables (for example, sleep and academic performance), the null hypothesis would predict that there is no relationship between those variables.

At a more technical level, the null hypothesis proposes that no statistical significance exists in a set of given observations and that any differences are due to chance alone.

And there you have it – hypotheses in a nutshell.

Very useful information. I benefit more from getting more information in this regard.

Very great insight,educative and informative. Please give meet deep critics on many research data of public international Law like human rights, environment, natural resources, law of the sea etc

In a book I read a distinction is made between null, research, and alternative hypothesis. As far as I understand, alternative and research hypotheses are the same. Can you please elaborate? Best Afshin

This is a self explanatory, easy going site. I will recommend this to my friends and colleagues.

Very good definition. How can I cite your definition in my thesis? Thank you. Is nul hypothesis compulsory in a research?

It’s a counter-proposal to be proven as a rejection

Please what is the difference between alternate hypothesis and research hypothesis?

It is a very good explanation. However, it limits hypotheses to statistically tasteable ideas. What about for qualitative researches or other researches that involve quantitative data that don’t need statistical tests?

In qualitative research, one typically uses propositions, not hypotheses.

could you please elaborate it more

I’ve benefited greatly from these notes, thank you.

This is very helpful

well articulated ideas are presented here, thank you for being reliable sources of information

Excellent. Thanks for being clear and sound about the research methodology and hypothesis (quantitative research)

I have only a simple question regarding the null hypothesis. – Is the null hypothesis (Ho) known as the reversible hypothesis of the alternative hypothesis (H1? – How to test it in academic research?

this is very important note help me much more

Thesis Vs Hypothesis: Understanding The Basis And The Key Differences

Hypothesis vs. thesis: They sound similar and seem to discuss the same thing. However, these terms have vastly different meanings and purposes. You may have encountered these concepts in school or research, but understanding them is key to executing quality work. 

In this article, I’ll discuss hypothesis vs. thesis, break down their differences, and show you how to apply this knowledge to create quality written works. Let’s get to it!

Thesis vs. Hypothesis: Understanding the Basis

The power of a thesis.

A thesis statement is typically found at the end of the introduction in an essay or research paper, succinctly summarizing the overarching theme.

Crafting a strong thesis

Hypothesis: the scientific proposition.

In contrast, a hypothesis is a tentative proposition or educated guess. It is the initial step in the scientific method, where researchers formulate a hunch to test their assumptions and theories. 

Formulating a hypothesis

Key differences between thesis vs. hypothesis, 1. nature of statement, 3. testability, 4. research stage, 6. examples.

These differences highlight the distinct roles that the thesis and hypothesis play in academic writing and scientific research, with one providing a point of argumentation and the other guiding the scientific inquiry process.

Can a hypothesis become a thesis?

Do all research papers require a thesis, can a thesis be proven wrong.

Yes. The purpose of a thesis is not only to prove but also to encourage critical analysis. It can be proven wrong with compelling counterarguments and evidence.

How long should a thesis statement be?

Is a hypothesis only used in scientific research, can a hypothesis be vague.

No. When creating a hypothesis, it’s important to make it clear and able to be tested. Developing experiments and making conclusions based on the results can be difficult if the hypothesis needs clarification.

Final Thoughts

In conclusion, understanding the differences between a hypothesis and a thesis is vital to crafting successful research projects and academic papers. While they may seem interchangeable at first glance, these two concepts serve distinct purposes in the research process. 

So, the next time you embark on a research project, take the time to ensure that you understand the fundamental difference between a hypothesis and a thesis. Doing so can lead to more focused, meaningful research that advances knowledge and understanding in your field.

Frequently asked questions

Should i use a research question, hypothesis, or thesis statement.

The way you present your research problem in your introduction varies depending on the nature of your research paper . A research paper that presents a sustained argument will usually encapsulate this argument in a thesis statement .

A research paper designed to present the results of empirical research tends to present a research question that it seeks to answer. It may also include a hypothesis —a prediction that will be confirmed or disproved by your research.

Frequently asked questions: Writing a research paper

A research project is an academic, scientific, or professional undertaking to answer a research question . Research projects can take many forms, such as qualitative or quantitative , descriptive , longitudinal , experimental , or correlational . What kind of research approach you choose will depend on your topic.

The best way to remember the difference between a research plan and a research proposal is that they have fundamentally different audiences. A research plan helps you, the researcher, organize your thoughts. On the other hand, a dissertation proposal or research proposal aims to convince others (e.g., a supervisor, a funding body, or a dissertation committee) that your research topic is relevant and worthy of being conducted.

Formulating a main research question can be a difficult task. Overall, your question should contribute to solving the problem that you have defined in your problem statement .

However, it should also fulfill criteria in three main areas:

• Researchability
• Feasibility and specificity
• Relevance and originality

Research questions anchor your whole project, so it’s important to spend some time refining them.

In general, they should be:

• Focused and researchable
• Answerable using credible sources
• Complex and arguable
• Feasible and specific
• Relevant and original

All research questions should be:

• Focused on a single problem or issue
• Researchable using primary and/or secondary sources
• Feasible to answer within the timeframe and practical constraints
• Specific enough to answer thoroughly
• Complex enough to develop the answer over the space of a paper or thesis
• Relevant to your field of study and/or society more broadly

A research aim is a broad statement indicating the general purpose of your research project. It should appear in your introduction at the end of your problem statement , before your research objectives.

Research objectives are more specific than your research aim. They indicate the specific ways you’ll address the overarching aim.

Once you’ve decided on your research objectives , you need to explain them in your paper, at the end of your problem statement .

Keep your research objectives clear and concise, and use appropriate verbs to accurately convey the work that you will carry out for each one.

I will compare …

Your research objectives indicate how you’ll try to address your research problem and should be specific:

Research objectives describe what you intend your research project to accomplish.

They summarize the approach and purpose of the project and help to focus your research.

Your objectives should appear in the introduction of your research paper , at the end of your problem statement .

The main guidelines for formatting a paper in Chicago style are to:

• Use a standard font like 12 pt Times New Roman
• Use 1 inch margins or larger
• Apply double line spacing
• Indent every new paragraph ½ inch
• Include a title page
• Place page numbers in the top right or bottom center
• Cite your sources with author-date citations or Chicago footnotes
• Include a bibliography or reference list

To automatically generate accurate Chicago references, you can use Scribbr’s free Chicago reference generator .

The main guidelines for formatting a paper in MLA style are as follows:

• Use an easily readable font like 12 pt Times New Roman
• Set 1 inch page margins
• Include a four-line MLA heading on the first page
• Center the paper’s title
• Use title case capitalization for headings
• Cite your sources with MLA in-text citations
• List all sources cited on a Works Cited page at the end

To format a paper in APA Style , follow these guidelines:

• Use a standard font like 12 pt Times New Roman or 11 pt Arial
• If submitting for publication, insert a running head on every page
• Apply APA heading styles
• Cite your sources with APA in-text citations
• List all sources cited on a reference page at the end

No, it’s not appropriate to present new arguments or evidence in the conclusion . While you might be tempted to save a striking argument for last, research papers follow a more formal structure than this.

All your findings and arguments should be presented in the body of the text (more specifically in the results and discussion sections if you are following a scientific structure). The conclusion is meant to summarize and reflect on the evidence and arguments you have already presented, not introduce new ones.

The conclusion of a research paper has several key elements you should make sure to include:

• A restatement of the research problem
• A summary of your key arguments and/or findings
• A short discussion of the implications of your research

Don’t feel that you have to write the introduction first. The introduction is often one of the last parts of the research paper you’ll write, along with the conclusion.

This is because it can be easier to introduce your paper once you’ve already written the body ; you may not have the clearest idea of your arguments until you’ve written them, and things can change during the writing process .

The introduction of a research paper includes several key elements:

• A hook to catch the reader’s interest
• Relevant background on the topic
• Details of your research problem

and your problem statement

• A thesis statement or research question
• Sometimes an overview of the paper

Dissertation vs Thesis: The Differences that Matter

Updated: June 19, 2024

Published: April 26, 2020

As a graduate student, you will have many different types of challenging coursework and assignments. However, the biggest project that you’ll work on when earning your master’s or doctoral degree will be your thesis or dissertation . The differences between a dissertation vs thesis are plenty. That’s because each of these pieces of writing happen at different times in one’s educational journey.

Let’s break down what a dissertation and thesis are so that you have a strong handle on what’s expected. For both a thesis and a dissertation, there is an obvious fluency and understanding of the subject one studies.

Let’s take a look at their similarities and differences.

What is a dissertation.

When you enter a doctoral program to earn a PhD, you will learn a lot about how to conduct your own research. At the culmination of your degree program, you’ll produce a dissertation.

A dissertation is a lengthy piece of written work that includes original research or expanded research on a new or existing topic. As the doctoral student, you get to choose what you want to explore and write about within your field of study.

What is a Thesis?

A thesis is also a scholarly piece of writing, but it is for those who are graduating from a master’s program. A thesis allows students to showcase their knowledge and expertise within the subject matter they have been studying.

Main Differences Between a Thesis vs. Dissertation

The biggest difference between a thesis and a dissertation is that a thesis is based on existing research.

On the other hand, a dissertation will more than likely require the doctoral student to conduct their own research and then perform analysis. The other big difference is that a thesis is for master’s students and the dissertation is for PhD students.

Structural Differences Between a Thesis and a Dissertation

Structurally, the two pieces of written analysis have many differences.

• A thesis is at least 100 pages in length
• A dissertation is 2-3x that in length
• A thesis expands upon and analyzes existing research
• A dissertation’s content is mostly attributed to the student as the author

Research Content and Oral Presentation

Once completed, some programs require students to orally present their thesis and dissertation to a panel of faculty members.

Typically, a dissertation oral presentation can take several hours. On the other hand, a thesis only takes about an hour to present and answer questions.

Let’s look at how the two scholarly works are similar and different:

Similarities:

• Each is considered a final project and required to graduate
• Both require immense understanding of the material
• Written skills are key to complete both
• Neither can be plagiarized
• Both are used to defend an argument
• Both require analytical skills
• You will have to draft, rewrite, and edit both pieces of writing
• For both, it is useful to have another person look over before submission
• Both papers are given deadlines

Differences:

• A dissertation is longer than a thesis
• A dissertation requires new research
• A dissertation requires a hypothesis that is then proven
• A thesis chooses a stance on an existing idea and defends it with analysis
• A dissertation has a longer oral presentation component

The Differences in Context: Location Matters

The united states.

In the US, everything that was previously listed is how schools differentiate between a thesis and a dissertation. A thesis is performed by master’s students, and a dissertation is written by PhD candidates.

In Europe, the distinction between a thesis and dissertation becomes a little more cloudy. That’s because PhD programs may require a doctoral thesis to graduate. Then, as a part of a broader post-graduate research project, students may complete a dissertation.

Each piece of writing is an opportunity for a student to demonstrate his or her ability to think critically, express their opinions in writing, and present their findings in front of their department.

Graduate degrees take a lot of time, energy, and hard work to complete. When it comes to writing such lengthy and informative pieces, there is a lot of time management that is involved. The purpose of both a thesis and a dissertation are written proof that you understand and have mastered the subject matter of your degree.

Degree Types

A doctoral degree, or PhD, is the highest degree that one can earn. In most cases, students follow the following path to achieve this level of education: Earn a bachelor’s degree, then a master’s, and then a PhD. While not every job title requires this deep educational knowledge, the salaries that come along with each level of higher education increase accordingly.

Earning Your Degree

Whether you are currently a prospective student considering earning your higher education degree or a student enrolled in a master’s or doctoral program, you know the benefits of education.

However, for some, earning a traditional degree on-campus doesn’t make sense. This could be because of the financial challenges, familial obligations, accessibility, or any other number of reasons.

For students who are seeking their higher education degrees but need a flexible, affordable, and quality alternative to traditional college, take a look at the programs that the University of the People has to offer.

Dissertation vs Thesis: Your 2024 Guide

If you’ve been thinking about going to graduate school, you may be familiar with the application requirements, rigorous academic schedule, and thesis or dissertation you’ll be expected to complete. So, what exactly is the difference between a thesis and a dissertation? While there are similarities, there’s a clear difference between the two. In our guide, we compare dissertation vs thesis. Discover more about both – and what you can expect during your graduate program. Let’s get started!

• Table of Contents

What Is a Thesis?

A thesis is an academic paper or project that’s completed towards the end of a master’s degree program . It is typically completed as the capstone project , meaning it’s the final project required for a student to graduate.

Students need to select a narrow, specific topic within – or relating to – their field of study. Once they’ve selected a topic, students must conduct an in-depth review of existing research on their chosen subjects. The next step is to formulate an academic argument, an assertion they’ll need to support or prove with said research.

Therefore, a thesis is akin to an in-depth research paper. It’s comprised of research that essentially proves what a student has learned during their program.

What Is a Typical Thesis Structure?

A thesis generally follows a rigid structure that’s decided by the program, department, or university. Here is an example of a thesis structure:

• The Title Page
• Summary of Thesis Abstract
• Table of Maps and Figures
• The Thesis Body (Sometimes divided into chapters)
• The Results or Conclusion

Who Needs to Complete a Thesis?

Most master’s degree programs require students to complete a thesis. While some undergraduate programs may also require a thesis, these are generally shorter and narrower in scope.

Some programs will also require a master’s student to defend their thesis in front of a panel or committee.

What Is a Dissertation?

What is “the PhD paper” called? Some people refer to it as a PhD thesis, but it’s most commonly known as a dissertation in the US. Dissertations are the capstone project required at the tail end of a PhD program . It is almost always required, except for a select few one-year PhD programs .

Much like a thesis, dissertations are also academic papers that aim to prove a student’s expertise – while adding to the current body of knowledge – in their field. Thus, a student must look at existing research and conduct their own research .

Basically, it’s the magnum opus of a doctoral journey in the United States. A dissertation isn’t just a long research paper; it’s a beast of a project. It demands extensive research, originality, and the ability to make a meaningful contribution to your chosen field. Think of it as a research odyssey guided by a seasoned mentor. Once you’ve conquered this scholarly quest and defended your findings, you’ll proudly emerge with your hard-earned doctoral degree, a testament to your dedication and scholarly prowess.

A dissertation typically comes after a PhD student completes their required courses and passes their qualifying exams. In some programs, the dissertation process is embedded into the coursework. In such cases, students receive a jump start on their work, allowing them to potentially finish their program earlier.

What Does a Dissertation Do?

PhD candidates must present a new theory or hypothesis. Alternatively, they must present their research to question (or disprove) the existing accepted theory on their chosen subject. Students may choose to tackle their topic from a new angle or take their research in a different direction.

Most programs will require students to defend their dissertations. During the defense, candidates must be able to justify the methodology of their research and the results and interpretation of their findings. Defenses are typically oral presentations in front of a dissertation committee , where the students are asked questions or presented with challenges.

Although the defense may seem daunting, PhD students work closely with their advisors to prepare for their dissertations. Students receive feedback and advice to guide their dissertations in their chosen direction.

What Is the Typical Dissertation Structure? 

Dissertations follow a rigid structure typically set by the program, department, or university. Here is an example format:

• The Acknowledgments Page
• The Abstract
• Introduction
• The Literature Review & Theoretical Framework
• The Methodology
• Findings/Results
• Discussions of the Findings, including analysis, interpretation, and applications
• The Conclusion
• List of References
• Any Appendices

What Is a Doctoral Thesis?

A doctoral thesis is a substantial piece of scholarly work that marks the pinnacle of a doctoral degree program, such as a PhD. Think of it as the academic grand finale. Its primary mission? To showcase the candidate’s mastery in their chosen field and their knack for delving deep into research.

In a nutshell, a doctoral thesis is a mammoth project that calls for originality. You’ve got to dig, investigate, gather data, crunch numbers, and present real data-supported findings. All this hard work usually happens under the watchful eye of a knowledgeable mentor. Once you’ve conquered this scholarly mountain and defended your thesis successfully, you’ll be proudly awarded your well-deserved doctoral degree. It’s the hallmark of your expertise and contribution to your field.

And how does a doctoral thesis differ from a dissertation? That’s mainly a geographic explanation. While they’re largely similar in scope and purpose, when comparing a doctoral thesis vs. a dissertation:

• A dissertation is the PhD capstone requirement in the US .
• A doctoral thesis is the PhD capstone requirement in Europe .

Dissertation vs. Thesis: The Similarities

In the master’s thesis vs dissertation discussion, there are plenty of similarities. Both are lengthy academic papers that require intense research and original writing. They’re also capstone projects which are completed at the tail end of their respective programs.

Students must work closely with their respective committees (e.g., faculty members, advisors, professionals) who provide feedback and guidance on their research, writing, and academic arguments. Both thesis and dissertation committees have a committee chair with whom the students work closely.

In some ways, the requirements for theses and dissertations are quite similar. They require a skillful defense of a student’s academic arguments. What’s more, both papers require critical thinking and good analytical reasoning, as well as in-depth expertise in the chosen field of study.

Students must also invest a significant amount of time into both projects while also being able to accept and action feedback on their work.

Dissertation vs. Thesis: The Differences

What are the differences between a PhD dissertation vs. thesis? The first and most distinct difference is the degree program requiring a PhD dissertation or thesis. A dissertation is typically the capstone project for a doctorate, while a thesis is the capstone project for a master’s degree program (or undergraduate program).

Candidates will have to defend their dissertation during an oral presentation in front of their committee. Only some master’s theses require this.

During a thesis, students typically conduct research by reviewing existing literature and knowledge on their chosen subject. During a dissertation, students must do their own research and prove their theory, concept, or hypothesis. They should also expect to develop a unique concept and defend it based on the practical and theoretical results achieved from their rigorous research.

Theses are also typically shorter (around 40 to 80 pages). Dissertations, however, are much longer (between 100 and 300 pages). Of course, the actual length of the paper may depend on the topic, program, department, or university.

Dissertations and Theses: US vs. Europe

Whether you’re in the US or Europe, dissertations and theses are similar. However, European requirements and conventions differ slightly:

Doctoral Thesis

To ensure your PhD graduation, a dissertation is generally required. Doctoral theses in Europe are much like a PhD dissertation in the US : You must complete your own research and add to the existing body of knowledge in your field.

Master’s Dissertation

It may seem odd to require a dissertation for master’s degree programs, but in Europe, this is exactly what you’ll need. A master’s dissertation is a broader post-graduate program research project , though it’s most typically required for master’s programs.

Frequently Asked Questions

Here are a few of the most common questions we hear about the meaning of thesis vs. dissertation.

Is a Thesis and a Dissertation the Same?

Yes and no. In some ways, a dissertation and a thesis are the same. For example, both require original writing, critical skills, analytical thinking, plenty of research, and lots of academic effort. However, a thesis is more commonly reserved for master’s – and some undergraduate – programs. Dissertations are generally required by PhD programs in the United States.

Additionally, a thesis typically calls for heavy research and compilation of existing knowledge and literature on a subject. A dissertation requires candidates to conduct their own research to prove their own theory, concept, or hypothesis – adding to the existing body of knowledge in their chosen field of study.

How Long Is a Thesis vs. a Dissertation?

One of the primary differences between thesis and dissertation papers is their length. While a thesis might be anywhere from 40 to 80 pages long, a dissertation can easily run from 100 to 300. It’s important to note that these numbers depend on the specific program and university.

Does a PhD Require a Thesis or a Dissertation?

It all depends on where you are! While a US-based PhD requires you to complete a dissertation, a thesis (or “doctoral thesis”) is more commonly required for PhD candidates in Europe. In the US, a thesis is more commonly reserved for master’s degree programs and occasionally undergraduate programs. In Europe, a “master’s dissertation” is typically required for the completion of a master’s degree.

So, there you have it: an in-depth comparison of the dissertation vs. thesis academic requirements. Now that you know the primary similarities and differences between the two, it might become easier to decide your academic path. Just remember, you may be able to find a master’s program without a thesis or a doctorate without a dissertation requirement if you prefer. Good luck!

Thesis vs. Dissertation: Understanding the Differences

A thesis and a dissertation are often used interchangeably, causing confusion among students and academics alike. While they share some similarities, they are distinct in purpose, scope, and requirements. Understanding these differences is crucial for graduate students embarking on their academic journey. In this article, we delve into the world of thesis and dissertation, shedding light on what sets them apart and helping you navigate these essential components of advanced academic research.

Thesis: The Master's Magnum Opus

In the realm of academia, a thesis is often referred to as the master's magnum opus, representing the pinnacle of a student's academic journey at the master's level. It is a significant undertaking that requires dedication, research acumen, and a commitment to scholarly excellence. Here, we explore the key characteristics and elements that define a thesis:

Academic Level: A thesis is a hallmark of master's degree programs. It serves as the culmination of a student's graduate studies, demonstrating their ability to engage critically with their field of study and contribute meaningfully to it. Unlike undergraduate projects, a thesis delves deeper into the subject matter and requires a higher level of analysis and synthesis.

Purpose: The primary purpose of a thesis is to contribute to the existing body of knowledge within a specific field or discipline. It goes beyond mere regurgitation of facts and concepts; it involves original research or a novel approach to addressing a research question or hypothesis. In essence, a thesis is a scholarly endeavor that aims to add value to the academic conversation.

Scope: Theses typically have a narrower scope compared to their doctoral counterparts, dissertations. While they explore complex topics, they often focus on a specific aspect or dimension within a broader field. This focused approach allows students to delve deeply into their chosen subject matter and demonstrate expertise in that area.

Length: Theses vary in length depending on the institution, program, and field of study. However, they are generally shorter than dissertations. A typical master's thesis can range from 50 to 100 pages. This concise format necessitates precision and clarity in presenting research findings and arguments.

Committee Evaluation: A key aspect of the thesis process is the evaluation by a committee of professors or advisors. This committee plays a pivotal role in guiding the student's research, offering feedback, and assessing the final product. Their expertise ensures that the thesis meets academic standards and contributes meaningfully to the field.

Research and Methodology: Research is at the heart of any thesis. Students engage in systematic inquiry, which may involve data collection, experimentation, surveys, literature analysis, or a combination of research methods. The methodology chosen should align with the research question and contribute to the overall quality of the thesis.

Scholarly Writing: A thesis demands scholarly writing of the highest caliber. Students are expected to adhere to academic writing conventions, including proper citation, referencing, and adherence to a specific style guide (e.g., APA, MLA). Clarity, coherence, and a formal tone are essential elements of thesis writing.

Originality: Perhaps the most crucial aspect of a thesis is its contribution to the field's body of knowledge. It must offer fresh insights, perspectives, or solutions to existing challenges. Originality is the hallmark of a well-executed thesis, distinguishing it from undergraduate assignments.

Dissertation: the doctoral opus.

In the realm of academia, a dissertation is the pinnacle of scholarly achievement within the context of doctoral programs. It represents the culmination of extensive academic preparation and research and is often referred to as the doctoral opus. Here, we explore the defining characteristics and elements that set a dissertation apart in the academic world:

Academic Level: A dissertation is synonymous with doctoral programs, such as a Doctor of Philosophy (Ph.D.) or other terminal degrees. It marks the highest level of academic achievement and signifies a student's readiness to make a significant contribution to their field.

Purpose: The primary purpose of a dissertation is to make a substantial and original contribution to the existing body of knowledge within a specific field or discipline. Unlike a thesis, which often focuses on a more specific aspect, a dissertation tackles complex research questions that have broader implications for the field.

Scope: Dissertations are renowned for their expansive scope. They typically explore multifaceted research questions that encompass multiple variables, perspectives, and dimensions. Doctoral candidates are expected to demonstrate a comprehensive understanding of their field and engage in in-depth analysis.

Length: Dissertations are considerably longer than theses. The length can vary depending on the field of study and the nature of the research, but they often exceed 100 pages and can extend to several hundred pages. This extended format allows for a thorough exploration of the research topic.

Committee Evaluation: A dissertation is rigorously evaluated by a committee of experts in the field. This committee plays a crucial role in guiding the research, offering feedback, and ultimately assessing the quality and significance of the dissertation. Their expertise ensures that the dissertation meets the highest academic standards.

Research and Methodology: Research in a dissertation is not only extensive but also often involves original data collection, experimentation, surveys, case studies, or longitudinal studies. The choice of research methodology is critical and should align with the research questions and objectives.

Scholarly Writing: As with theses, scholarly writing is paramount in dissertations. Doctoral candidates are expected to adhere to the most stringent academic writing conventions. This includes precise citation and referencing, adherence to a specific style guide, and the use of formal and rigorous language.

Originality: The hallmark of a successful dissertation is its originality. It must offer new insights, perspectives, or solutions to complex problems within the field. Doctoral candidates are expected to demonstrate their ability to contribute significantly to the advancement of knowledge.

Defending the Dissertation: A distinctive feature of the dissertation process is the formal defense. Candidates present their research findings and defend their methodology, conclusions, and contributions before their committee and often a public audience. This oral defense is a culmination of the rigorous research journey.

What is the difference between hypothesis, thesis statement and research goal?

Can someone explain the difference between hypothesis, thesis statement and research goal based on an example?

• terminology

• 1 You should mention which subject you are in. 'Hypothesis' has opposite meanings in maths and physics. –  Jessica B Commented May 31, 2018 at 11:22

I had this same question recently and did some research on it. The definitions I found weren't consistent, but from them I derived the following.

Thesis statement -- A definitive statement about the way the world (or your system of interest) works, especially what is most important in causing or influencing the behavior of the system.

"Family expectations has primary significance on the performance in college for Latino girls in the Western US" is an example of a thesis statement.

Research goal -- Expresses what you hope to learn or shed light on in your research. Specifically, the goal should specify what type of results you are hoping to achieve. It contextualizes your work in relation to other research, especially theory. It also feeds into your choice of method.

"My research goal is to develop a theoretical model of cultural influence on college performance, contextualized by gender and ethnicity" is an example of a research goal.

Hypotheses -- What specific conditions or relations do you aim to test or evaluate in your research. Any research that does not include a method for hypothesis testing should not claim to test hypotheses. A hypothesis statement must be specific enough that it is testable by the methods you choose, and also it should be falsifiable -- i.e. it is clear what evidence might prove the hypothesis false, and such evidence should be plausible and possible.

"Low family expectations has a detrimental effect on the college completion rate and time-to-complete for high-achieving Latino girls" is an example of a hypothesis statement.

Notice how there are specific, testable conditions and metrics -- "college completion rates" and "time-to-complete". These conditions should appear as metrics in your research methods -- i.e. instruments and analysis methods.

A thesis statement usually helps guide the research paper. It is a short sentence or summary containing the central idea of the research paper. It helps a reader have a clear glimpse of what the paper is about.

The Hypothesis statement comes in different format but with the intent to help prove or disprove a phenomenon. The hypothesis can help defend, support, explain or disprove, argue against the thesis statement.Usually the hypothesis measures specific issues or variables-two or more and therefore should be testable. The thesis statement creates a background while the hypothesis creates a means to measure the interrelationship.

The research goal takes a look into the future of your study or research paper. |It tries to help you state what the outcomes you seek to achieve by the research work. With a research goal you can set specific milestones to accomplish at the end of the research work.

Assumption vs. Hypothesis

What's the difference.

Assumption and hypothesis are both concepts used in research and reasoning, but they differ in their nature and purpose. An assumption is a belief or statement that is taken for granted or accepted as true without any evidence or proof. It is often used as a starting point or a premise in an argument or analysis. On the other hand, a hypothesis is a tentative explanation or prediction that is based on limited evidence or prior knowledge. It is formulated to be tested and verified through empirical research or experimentation. While assumptions are often subjective and can be biased, hypotheses are more objective and aim to provide a basis for scientific investigation.

Further Detail

Introduction.

Assumptions and hypotheses are fundamental concepts in the fields of logic, science, and research. While they share some similarities, they also have distinct attributes that set them apart. In this article, we will explore the characteristics of assumptions and hypotheses, their roles in different contexts, and how they contribute to the process of knowledge acquisition and problem-solving.

Assumptions

An assumption is a belief or statement that is taken for granted or accepted as true without any proof or evidence. It serves as a starting point for reasoning or argumentation. Assumptions can be based on personal experiences, cultural norms, or generalizations. They are often used to fill in gaps in knowledge or to simplify complex situations.

One key attribute of assumptions is that they are not necessarily true or proven. They are subjective and can vary from person to person. Assumptions can be implicit, meaning they are not explicitly stated, or explicit, where they are clearly expressed. They can also be conscious or unconscious, depending on whether we are aware of them or not.

Assumptions play a crucial role in everyday life, decision-making, and problem-solving. They help us make sense of the world and navigate through uncertain situations. However, it is important to recognize that assumptions can introduce biases and limit our understanding if they are not critically examined or challenged.

A hypothesis, on the other hand, is a tentative explanation or prediction that is based on limited evidence or prior knowledge. It is formulated as a testable statement that can be supported or refuted through empirical observation or experimentation. Hypotheses are commonly used in scientific research to guide investigations and generate new knowledge.

Unlike assumptions, hypotheses are grounded in evidence and are subject to verification. They are formulated based on existing theories, observations, or logical reasoning. Hypotheses are often stated in the form of "if-then" statements, where the independent variable (the "if" part) is manipulated or observed to determine its effect on the dependent variable (the "then" part).

Hypotheses are essential in the scientific method, as they provide a framework for conducting experiments and gathering data. They allow researchers to make predictions and draw conclusions based on empirical evidence. If a hypothesis is supported by the data, it can lead to the development of theories or further research. If it is refuted, it may prompt the formulation of new hypotheses or the revision of existing ones.

Comparison of Attributes

While assumptions and hypotheses share the commonality of being statements or beliefs, they differ in several key attributes:

Assumptions are often based on personal beliefs, experiences, or cultural norms. They can be influenced by subjective factors and may not have a solid foundation in evidence or logic. In contrast, hypotheses are grounded in existing knowledge, theories, or observations. They are formulated based on logical reasoning and are subject to empirical testing.

2. Verifiability

Assumptions are not easily verifiable since they are often subjective or based on incomplete information. They are accepted as true without rigorous testing or evidence. On the other hand, hypotheses are formulated to be testable and verifiable. They can be supported or refuted through empirical observation or experimentation.

Assumptions are primarily used to simplify complex situations, fill in gaps in knowledge, or provide a starting point for reasoning. They are often employed in everyday life, decision-making, and problem-solving. Hypotheses, on the other hand, serve the purpose of generating new knowledge, guiding scientific research, and making predictions about the relationship between variables.

4. Role in Knowledge Acquisition

Assumptions can limit knowledge acquisition if they are not critically examined or challenged. They can introduce biases and prevent us from exploring alternative explanations or perspectives. Hypotheses, on the other hand, contribute to knowledge acquisition by providing a structured approach to testing and refining ideas. They encourage critical thinking, data collection, and analysis.

5. Testability

Assumptions are often difficult to test since they are not formulated as specific statements or predictions. They are more subjective in nature and may not lend themselves to empirical verification. Hypotheses, on the other hand, are designed to be testable. They are formulated as specific statements that can be supported or refuted through observation or experimentation.

Assumptions and hypotheses are both important concepts in reasoning, problem-solving, and scientific research. While assumptions provide a starting point for reasoning and decision-making, hypotheses offer a structured approach to generating new knowledge and making predictions. Understanding the attributes and differences between assumptions and hypotheses is crucial for critical thinking, avoiding biases, and advancing our understanding of the world.

Many students may have a hard time understanding the differences between a thesis, a hypothesis, and a theory. It is important to understand their differences. Such an understanding will be instrumental.

More so, when writing complex research papers that require a thesis that has a hypothesis and utilizes theories. We have gathered from responses of our college writing service that the difference between the three is confusing.

That being said, this article is meant to explain the differences between a thesis, a hypothesis, and a theory. 

Difference between Hypothesis and Thesis

There are major differences between hypothesis and thesis. While they seem to be related on the face, their differences are huge both in concept and practice.

A hypothesis is a proposed explanation of something or a phenomenon. A scientific hypothesis uses a scientific method that requires any hypothesis to be tested. As such, scientists and researchers base their hypothesis on observations that have been previously made and that which cannot be explained by the available or prevailing scientific theories.

From the definition of a hypothesis, you can see that theories must be included in any scientific method. This is the reason why this article tries to differentiate a thesis, a hypothesis, and a theory. 

Moving forward, a thesis can be defined as a written piece of academic work that is submitted by students to attain a university degree. However, on a smaller scale, there is something that is referred to as a thesis statement.

This is written at the introduction of a research paper or essay that is supported by a credible argument. The link between a hypothesis and thesis is that a thesis is a distinction or an affirmation of the hypothesis.

What this means is that whenever a research paper contains a hypothesis, there should be a thesis that validates it.

What is a Hypothesis?

A hypothesis can be defined as the proposed or suggested explanation for an occurrence, something, or a phenomenon. It should be testable through scientific methods. The reason why scholarly works should have a hypothesis is that the observed phenomena could not be explained using the prevailing scientific theories hence the reason why it should be tested. 

Testing the hypothesis may result in the development of new or improved scientific theories that are beneficial to the discipline and society in general. 

What is a Thesis?

A thesis is a written piece of academic work that is submitted by students to attain a university degree. When a thesis is used as a stand-alone word, it denotes academic papers written by university students. It is mostly written by those pursuing postgraduate degrees, at the end of their courses. They demonstrate their proficiency in their disciplines and the topics they have selected for research. 

However, when a thesis is used to refer to a statement, it denotes the statement that is written at the introduction of a research paper or essay. A thesis is supported by a credible argument.

Every research paper must have a thesis statement that acts as a guide to what the research will be all about. It is possible to receive very poor grades or even score a zero if your research paper lacks the thesis statement. 

What is a Theory?

A theory can be defined as a rational form of abstract perspectives or thinking concerning the results of such thinking or a phenomenon. The process of rational and contemplative thinking is mostly associated with processes such as research or observational study.

As such, a theory can be considered to belong to both scientific and non-scientific disciplines. Theories can also belong to no discipline.

From a modernistic scientific approach, a theory can mean scientific theories that have been well confirmed to explain nature and that are created in such a way that they are consistent with the standard scientific method. A theory should fulfill all the criteria required by modern-day science. 

A theory should be described in a way that scientific tests that have been conducted can provide empirical support or contradiction to the theory.

Because of the nature by which scientific theories are developed, they tend to be the most rigorous, reliable, and comprehensive when it comes to describing and supporting scientific knowledge. 

The connection between a theory and a hypothesis is that when a theory has not yet been proven, it can be referred to as a hypothesis.

The thing about theories is that they are not meant to help the scientist or researcher reach a particular goal. Rather, a theory is meant to guide the process of finding facts about a phenomenon or an observation.

Difference between a Theory and Thesis

A theory is a rational form of abstract perspectives or thinking concerning the results of such thinking or a phenomenon. The process of rational and contemplative thinking is mostly associated with processes such as research or observational study. On the other hand, a thesis is a written piece of academic work that is submitted by students to attain a university degree.

It denotes academic papers that are written by students in the university, especially those pursuing postgraduate degrees, at the end of their courses to demonstrate their proficiency in their disciplines and the topics they have selected for research. 

To understand the application of these, read our guide on the difference between a research paper and a thesis proposal to get a wider view.

How to write a Good Hypothesis

1. asking a question.

Asking a question is the first step in the scientific method and the question should be based on  who, what, where, when, why,  and  how . The question should be focused, specific, and researchable.

2. Gathering preliminary research 

This is the process of collecting relevant data. It can be done by researching academic journals, conducting case studies, observing phenomena, and conducting experiments. 

3. Formulating an answer

When the research is completed, you should think of how best to answer the question and defend your position. The answer to your question should be objective. 

4. Writing the hypothesis

When your answer is ready, you can move to the next step of formulating the hypothesis. A good hypothesis should contain relevant variables, predicted outcomes, and a study group that can include non-human things. The hypothesis should not be a question but a complete statement. 

5. Refining the hypothesis

Though you may skip this step, it is advisable to include it because your study may involve two groups or be a correlational study. Refining the hypothesis will ensure that you have stated the difference or relationship you expect to find. 

6. Creating a null and alternative hypotheses

A null hypothesis (H0) will postulate that there is no evidence to support the difference. On the other hand, an alternative hypothesis (H1) posits that there is evidence in support of the difference.

Thesis:  High levels of alcohol consumption have detrimental effects on your health, such as weight gain, heart disease, and liver complications.

Hypothesis:  The people who consume high levels of alcohol experience detrimental effects on their health such as weight gain, heart disease, and liver complications. 

What is the difference between a summary and a thesis statement?

A summary is a brief account or statement of the main points from the researches. A thesis statement is a statement that is written at the end of the introduction of a research paper or essay that summarizes the main claims of the paper. 

Difference between hypothesis and statement of the problem

A hypothesis can be defined as the proposed or suggested explanation for an occurrence, something, or a phenomenon. The same should be testable through scientific methods. Conversely, a statement of a problem is a concise description of the issue to be addressed on how it can be improved.

Research Questions vs Hypothesis: What’s The Difference?

by  Antony W

August 1, 2024

You’ll need to come up with a research question or a hypothesis to guide your next research project. But what is a hypothesis in the first place? What is the perfect definition for a research question? And, what’s the difference between the two?

In this guide to research questions vs hypothesis, we’ll look at the definition of each component and the difference between the two.

We’ll also look at when a research question and a hypothesis may be useful and provide you with some tips that you can use to come up with hypothesis and research questions that will suit your research topic . 

Let’s get to it.

What’s a Research Question?

We define a research question as the exact question you want to answer on a given topic or research project. Good research questions should be clear and easy to understand, allow for the collection of necessary data, and be specific and relevant to your field of study.

Research questions are part of heuristic research methods, where researchers use personal experiences and observations to understand a research subject. By using such approaches to explore the question, you should be able to provide an analytical justification of why and how you should respond to the question. 

While it’s common for researchers to focus on one question at a time, more complex topics may require two or more questions to cover in-depth.

When is a Research Question Useful? 

A research question may be useful when and if: 

• There isn’t enough previous research on the topic
• You want to report a wider range out of outcome when doing your research project
• You want to conduct a more open ended inquiries 

Perhaps the biggest drawback with research questions is that they tend to researchers in a position to “fish expectations” or excessively manipulate their findings.

Again, research questions sometimes tend to be less specific, and the reason is that there often no sufficient previous research on the questions.

What’s a Hypothesis? 

A hypothesis is a statement you can approve or disapprove. You develop a hypothesis from a research question by changing the question into a statement.

Primarily applied in deductive research, it involves the use of scientific, mathematical, and sociological findings to agree to or write off an assumption.

Researchers use the null approach for statements they can disapprove. They take a hypothesis and add a “not” to it to make it a working null hypothesis.

A null hypothesis is quite common in scientific methods. In this case, you have to formulate a hypothesis, and then conduct an investigation to disapprove the statement.

If you can disapprove the statement, you develop another hypothesis and then repeat the process until you can’t disapprove the statement.

In other words, if a hypothesis is true, then it must have been repeatedly tested and verified.

The consensus among researchers is that, like research questions, a hypothesis should not only be clear and easy to understand but also have a definite focus, answerable, and relevant to your field of study. 

When is a Hypothesis Useful?

A hypothesis may be useful when or if:

• There’s enough previous research on the topic
• You want to test a specific model or a particular theory
• You anticipate a likely outcome in advance 

The drawback to hypothesis as a scientific method is that it can hinder flexibility, or possibly blind a researcher not to see unanticipated results.

Research Question vs Hypothesis: Which One Should Come First 

Researchers use scientific methods to hone on different theories. So if the purpose of the research project were to analyze a concept, a scientific method would be necessary.

Such a case requires coming up with a research question first, followed by a scientific method.

Since a hypothesis is part of a research method, it will come after the research question.

Research Question vs Hypothesis: What’s the Difference? 

The following are the differences between a research question and a hypothesis.

We look at the differences in purpose and structure, writing, as well as conclusion. 

Research Questions vs Hypothesis: Some Useful Advice 

As much as there are differences between hypothesis and research questions, you have to state either one in the introduction and then repeat the same in the conclusion of your research paper.

Whichever element you opt to use, you should clearly demonstrate that you understand your topic, have achieved the goal of your research project, and not swayed a bit in your research process.

If it helps, start and conclude every chapter of your research project by providing additional information on how you’ve or will address the hypothesis or research question.

You should also include the aims and objectives of coming up with the research question or formulating the hypothesis. Doing so will go a long way to demonstrate that you have a strong focus on the research issue at hand.

Dissertation vs Thesis: Differences and Similarities

Getting a graduate degree, whether it is a master or a doctoral degree is highly challenging. These degrees are all comprised of advanced courses and expect students to be constantly engaged with the material. Both a master’s and a doctoral program mean that the student is on his or her way to become an expert in the field.

In order to succeed in these advanced degrees, students need to complete all coursework by doing the readings, projects, and the necessary research. Whereas a Bachelor’s Degree only goes over subjects of interest in a more superficial manner, still giving students time to commit to a field, students doing a master’s and doctoral degrees take one field of study and explore it in depth.

Besides the necessary courses that are required for a graduate degree most programs also involve the completion of an advanced piece of work in research, either a thesis or a dissertation. Thesis or dissertations are the final pieces of work that students submit before graduation and they encompass all the skills and knowledge that has been accumulated during the years of study for the degree.

Most people use the words thesis and dissertation interchangeably, meaning that one could substitute the other and they are the same. There are so many academic terms now that it is easy to confuse them. However, there are similarities and differences in both the thesis and the dissertation , and this article will explore them.

• What are a thesis and a dissertation?
• Similarities of thesis and dissertation
• Differences between thesis and dissertation

What Are A Thesis And A Dissertation?

The thesis and dissertation are both academic papers which focus on the field of study of the student. They are both research focused and explore a topic in depth, bringing together all concepts, theories, and practical applications which have been acquired during the years that a student has been in graduate school, whether it is a master’s or a doctoral (PhD) program.

Similarities Of Dissertation and Thesis

The terms of thesis and dissertation are used as if they were the same, and there are quite a few similarities between them. These include the fact that both projects are for graduate students and not for undergraduate students. In addition, they are both lengthy papers , often surpassing hundreds of pages depending on the field of study and whether they are more theoretical or practical.

Completing thesis or dissertation

Also, both projects require some sort of guidance to complete. That is why mentors or advisers are assigned to students to help them along the way and give them advice on how to proceed. The advisers or mentors comment on the student’s research plans, writing, collection of data and so on. At the end, they are mentioned in the final project as main contributors besides the author or student.

Since the thesis and dissertation are required for students to be allowed to graduate, those who undertake to do these projects must get a passing grade . This passing grade is usually considered to be a B or above . Due to the mentorship and effort that students give to complete either a thesis or a dissertation, they usually get good grades.

In case a student does not get a passing grade , many universities have policies on letting students redo or rewrite their thesis or dissertation . However, there are limits on the number of times students are allowed to redo their research projects. These limits depend on the university which is awarding the degree.

Moreover, both the dissertation and the thesis have similar structures that students need to write.

• Introduction
• Literary Review
• Bibliography

Even though these parts have the same names, their contents will be quite different.

Thesis or dissertation defense

After students complete their dissertations or thesis projects they are required to present them . Most universities require oral presentations or as they are called thesis or dissertation defenses. This means that students will present and defend their work and arguments in front of a panel of professors, mentors, industry experts, peers, as well as family members. The audience will ask questions at the end to test whether the student has done good work and to see how valid the project is. At the end, the professors will evaluate the research project and will grade them.

Whether you choose a thesis or a dissertation depends on a few factor s, however through completing one or the other you will be doing the following:

• Developing a sound research proposal
• Exploring a specific research question of your interest in depth
• Identifying the necessary resources for your research
• Analyzing and reviewing relevant literature
• Choosing and applying the appropriate research methodology for your research question
• Analyzing, interpreting, and reporting the data and findings
• Identifying lessons learned or implications of your research for a wider scope

Differences Between Thesis And Dissertation

A thesis and a dissertation despite being used interchangeably, also have many differences in various aspects. Below we will give details on the 5 main differences of a thesis and dissertation.

Country differences in definition

Because different countries or continents in general have different educational systems, the definitions of various academic terms will also not be the same. This stands for the dissertation vs thesis concepts, more specifically the differences are in Europe and the United States .

In Europe, a thesis is a requirement to graduate from a doctoral or PhD program . It is a large body of original research that the student does over several years, which also contains references and relations to existing research that has been done by other people.

The dissertation on the other hand is a smaller research project that is done to complete a Master’s program. It does not necessarily need to have original research, but the student must take a view and back it up with arguments collected from existing research in the form of literature review.

The United States

In the United States, the definitions of a thesis and dissertation are completely opposite. The thesis in this case is the research project necessary for graduating from a master’s degree program , while the dissertation is done for doctoral degrees .

So the thesis will contain the arguments developed mostly from existing research , while the dissertation will be complete when the student picks a topic which has not been explored yet and dedicates years to researching it and prove or disprove a hypothesis .

In this article, we will explore the difference between thesis and dissertation from the U.S perspective and definitions.

Type of Degree

The dissertation vs thesis difference is in what they are used for. The dissertation will be used to get the terminal degree or the highest qualification possible in different fields such as the doctoral or PhD degree .

On the other hand, the thesis is used to mark the end of a master’s degree , so students will get their second cycle qualifications or education after their Bachelor’s Degree by presenting their thesis.

There are also cases when a thesis or dissertation is not required and this depends on the type of program or institution that the student is completing their degree in. This mostly occurs with master’s degrees rather than PhD programs. Some masters programs will give students a choice between doing their thesis or completing an additional course.

It is recommended that if students aim to continue their education and get a PhD qualification that they choose to complete the thesis instead of the course. That is because completing a thesis will add to your research experience and PhD programs will be more likely to accept you if you have already published some form of research.

It is also better to do the thesis if you plan to get a PhD since the dissertation requires more extensive work than the thesis, so you will already have a basic understanding of the effort and work it takes to complete it.

Data Collection

Another difference between thesis and dissertation is the way in which students go through the data collection process.

Since the dissertation is the original research for which students graduate from a PhD, it mostly uses primary data such as:

• Questionnaires or surveys
• Focus Groups
• Any other form of data collected by the student

The thesis which does not necessarily require primary data collection, relies more on secondary data such as:

• Survey reports
• Existing studies
• Government or official statistics, etc.

The dissertation focuses on primary data , but uses secondary sources to back arguments and provide evidence for or against a certain hypothesis. The thesis on the other hand may or may not contain primary data , and it all depends on the student’s choice.

Purpose of study

The purpose of each of the research projects is different.

A thesis is mostly the usage of secondary sources to demonstrate to your professors and peers that you have gained enough information and skills in your field of interest. The thesis starts with a proposition and then the student analyzes and makes a case for their point of view.

The purpose of the dissertation is completely different from the thesis. The dissertation is done in order to contribute to the advancement of your field through discovering new knowledge based on research . Those who do a dissertation try to discover new concepts and theories which have not been researched enough before. They have a hypothesis and use quantitative and qualitative primary data to prove or disprove it.

Length of project

Lastly, another difference between the thesis and dissertation is in their length .

Because the dissertation is original research, it can be as long as 400 pages so it will basically be a book on your topic of interest.

The thesis though relies on secondary sources and does not go as in depth into the subject as the dissertation, so its length is minimum 100 pages , but it is not necessarily a whole book about a subject.
