Thesis vs Dissertation: What Are the Differences?

Thesis vs Dissertation: What Are the Differences?

In order to graduate from a graduate program, students must complete a significant research and writing project, such as a thesis for a master’s program or a dissertation for a doctoral program. What distinguishes a dissertation from a thesis, why these two terms are always mixed up? There are some key distinctions and parallels between the two that prospective graduate students should be aware of. In this blog post, we will explain Dissertation vs Thesis UK, their types, differences, and similarities. 

What Exactly Is A Thesis?

A thesis is a piece of academic writing that is finished toward the end of a student’s master’s degree program. A thesis must typically be finished in order to earn a master’s degree. Even writing an undergraduate thesis, which is typically shorter and less in-depth than a master’s degree thesis, is a requirement for some bachelor’s degree programs.

Students choose an area of interest in their field that is reasonably narrow for their master’s thesis. For instance, if you’re pursuing a degree in nutrition science, you might investigate how different pregame meal compositions affect athletic performance.

Conducting a thorough review of the prior research on your subject comes next. Then, you would develop a rational argument (such as that high-carb pre-game meals are advantageous for endurance athletes) and use the available data to support your claim.

Depending on the regulations of the university and the specific department, a thesis is typically formatted in a fairly rigid manner. Frequently needed are the elements listed below: 

  1. Page title
  2. a succinct summary
  3. Index of the Contents
  4. Figures/Maps Table
  5. Chapters usually make up the body.
  6. Conclusion/results

Types Of Thesis Statements

Thesis statements may be analytical, argumentative, or explanatory. The thesis statement’s format depends on the kind of paper being written.

1. An explanation of the main idea

The only supporting evidence for an explanatory thesis statement is factual data. It doesn’t include personal opinions or makes assertions without supporting data. Instead, it clearly states the topic and briefly mentions the main ideas that will be covered in the essay. A thesis statement that provides an explanation is sometimes referred to as an expository thesis statement.

2. A strong argumentative thesis

In an argumentative essay, the author adopts a position on a contentious subject. The position taken and the justifications for it make up the argument. An argumentative thesis statement, as opposed to an explanatory one, enables the writer to take a position on a subject and persuade readers of that position (for example, the deeper meaning of a literary work or the best course of action for a social issue).

3. A strong analytical thesis

A thesis statement that analyzes or deconstructs a problem or idea into its component parts. The topic is then evaluated, and the reader is then given a clear explanation of the analysis’s order.

One such benefit was that students were more alert and attentive in class, had a more positive attitude toward school, and performed better on their coursework as a result of the school’s decision to start the school day an hour later.

What is a Dissertation?

In a dissertation vs thesis UK, unlike a thesis, a doctoral dissertation requires students to conduct their own original research after reviewing previously published work. The goal of a dissertation is not only to prove the student’s own knowledge and skills but also to add something more to the existing body of knowledge in their field.

A new theory or hypothesis in their field may be presented by students, or they may present data that refutes an established theory. Alternately, they might take on a fresh approach, moving the existing research in a different direction.

Similar to how a master’s thesis is written, a dissertation starts out similarly. Students choose a topic and then conduct a literature review, which is a detailed examination of the pertinent research that has already been done. From there, students can begin developing a new theory, refuting an existing theory, or exploring an existing theory from a different perspective.

The structure of a dissertation, like that of a thesis, is determined by the rules and specifications of the university and the doctoral candidate’s department. 

Dissertations typically contain the following:

  1. Title page
  2. Acknowledgments
  3. Abstract
  4. The contents
  5. Introduction
  6. Review of the literature and theoretical foundation
  7. Methodology
  8. Findings
  9. Analyses, interpretations, and applications of the results are discussed.
  10. Conclusion
  11. list of references
  12. Appendices

Different Types Of Dissertations

Dissertations come in a variety of formats, depending on the research they involve and how they are presented to a panel of academics and subject-matter experts. To help you get one step closer to receiving your doctorate, we’ll concentrate on the three main categories of dissertation research in this article of Premium Dissertation Help on dissertation vs thesis UK.

Qualitative Dissertations

A qualitative dissertation is the first category of the dissertation. The qualitative research that a doctoral candidate would carry out over the course of their studies is mirrored in a qualitative dissertation. The non-numerical data used in this kind of research is gathered through methods like participant observation, focus groups, and interviews. 

The choice to use the qualitative method for your dissertation research will be largely influenced by the data that you are gathering. For instance, a qualitative approach might be appropriate for dissertation research in the fields of psychology or education, depending on the focus of the study. A candidate may pursue one or more of the following within a qualitative dissertation research model:

  • research using cases
  • Autoethnography
  • research in narrative 
  • logical argument 

Qualitative dissertations typically contain certain fundamental characteristics, despite the possibility of individual approaches varying. For instance, the kind of research used to create a qualitative dissertation frequently employs an emergent design, in which the subject matter and research approach modify over time. Candidates also use research paradigms to further plan out the most effective way to gather and communicate their findings. To name a few, these include interpretivism, constructivism, and critical theory. 

Doctoral candidates who conduct qualitative dissertation research have a variety of presentation methods available to them when it comes time to share their findings. Case studies, individual research findings, stories, observations, and abstracts are some of the choices made. Their presentation focuses on conceptual understandings supported by pertinent data. 

2. Quantitative Dissertations

On the other hand, quantitative dissertation research focuses on data. Candidates gather data that is simple to categorize and analyze using quantitative research techniques. In addition to performing conventional statistical analysis, quantitative research also fine-tunes a particular research approach depending on the nature of the research questions. Additionally, replication-based studies, data-driven dissertations, and theory-driven research are all options for quantitative candidates. 

Some candidates who rely on quantitative measures in their research concentrate on testing accepted theories, whereas others develop an original strategy. Quantitative researchers concentrate on positivist or post-positivist research paradigms to hone their methodology. Descriptive, experimental, or relationship-based designs are just a few examples of the types of designs used in quantitative research. 

Researchers concentrate on using questionnaires and surveys, structured interviews and observations, data sets, and laboratory-based methods to gather the actual data. When it comes time to evaluate the quality of the data, quantitative researchers compare their findings to a set of standards, such as reliability, internal and external validity, and construct validity. When presenting their findings, quantitative researchers have options. Candidates present their findings with the help of graphs, statistics, tables, and analytical claims.

Mixed-Method Dissertations

Many Ph.D. candidates also employ a hybrid model, which combines qualitative and quantitative research techniques. Models for mixed dissertation research are still relatively new but gaining popularity. A mixed-method approach offers candidates versatility and credibility for a number of different reasons. It’s a more all-encompassing approach that enables greater data collection and presentation optimization. 

The majority of the time, candidates will begin by gathering and classifying their data using quantitative techniques. After that, they will use qualitative analysis techniques to make sense of the data and present their committee panel with their findings. 

While using a mixed-method approach allows you to gather and analyze a wider variety of data, you run the risk of expanding the scope of your dissertation research to the point where you are unable to draw clear, enduring conclusions. In order to thoroughly examine the data collection methods you use, it is crucial that you clearly define your research objectives and strategy early on in the dissertation writing process. 


Dissertation vs Thesis UK: Some Common Differences

Some common differences between dissertation vs thesis UK are mentioned below:


  • The timing of when they are finished is the main distinction between a thesis and a dissertation. A dissertation is presented to earn a Ph.D., as opposed to a thesis, which is presented at the conclusion of a master’s program, as was previously mentioned.
  • A thesis is a compilation of research that shows the researcher is knowledgeable about the research topic and has learned it through their academic program. On the other hand, a dissertation gives the researcher the chance to add fresh ideas and knowledge to the body of literature already present in the field.
  • A thesis presents newly learned and already-known material, whereas a dissertation seeks to develop a novel idea and support it with theoretical and practical data.
  • The average length of a master’s thesis is 100 pages. A Ph.D. dissertation, on the other hand, should be much longer than a thesis and contain background and research information. Your research topic ideation, grant application, literature review, research proposal, and every other relevant detail about your study must all be included in your dissertation. The ideal length of a dissertation should be three times that of a master’s thesis, taking into account all the information mentioned above.

Dissertation vs Thesis UK: Differences In The Structure

A master’s thesis resembles the types of research papers you are used to writing during your undergraduate studies. After conducting research on a topic, you analyze the data you found and make comments about how it relates to the topic at hand. The purpose of the thesis is to demonstrate your capacity for critical analysis of a subject and for in-depth, informed discussion of the data. Additionally, when writing a thesis, you typically use this time to elaborate on a topic that is most pertinent to the professional specialty you want to pursue. When writing a dissertation, you should only use the work of others as a guide for developing and supporting your own original hypothesis, theory, or concept. In a dissertation, you are given credit for the majority of the information.

Finally, these two important works are different in length. A master’s thesis should be at least 100 pages long, and most are a little longer. According to Purdue University, a doctoral dissertation should be considerably longer because it includes a substantial amount of background and research information, as well as every aspect of your proposal and how you arrived at the information. An extremely difficult piece of writing is a dissertation. It’ll probably be twice as long as a thesis, maybe even three times as long. Your dissertation adviser will be a member of the faculty who will offer guidance to you. If you get stuck, this advisor will be able to point you in the right direction, help you find resources, and make sure your proposal is on the right track.


Dissertation vs Thesis UK: Similarities

These similarities of dissertation vs thesis UK are:


  • Both a thesis and a dissertation are regarded as a program’s capstone project and are necessary for graduation.
  • Both the dissertation and the thesis require a thorough and precise understanding of the research problem.
  • Specific research questions must be addressed in both types of scholarly writing.
  • Both a thesis and a dissertation require strong academic writing abilities.
  • The collection and documentation of research data must adhere to ethical standards.
  • Both places prohibit plagiarism.
  • To support the findings, both require analytical abilities.
  • Before final submission, both the thesis and the dissertation must undergo extensive editing and critical proofreading.


Contextual Variations: Location Is Important

The United States

Based on the aforementioned criteria, US schools distinguish between a thesis and a dissertation. A master’s student completes a thesis, whereas a Ph.D. candidate writes a dissertation.


The initial distinction between a dissertation vs thesis UK has largely been upheld in Europe. In order to earn a Ph.D., candidates must complete a focused original research project known as a doctoral thesis. A dissertation is a component of a larger post-graduate research undertaking.


The thesis has changed because the current original research demands extensive background reading. A thesis will therefore include numerous citations and references to earlier works, even though the emphasis is still on the original work that results from it.



The facts about the dissertation vs thesis UK are undoubtedly accurate. Therefore, it is improper for academic writing to substitute one term for another. Each must be used in accordance with its intended purpose. But neither one is compromised by the other. Both dissertation vs thesis UK writing requires the same level of seriousness. Technical and soft skills are essential for both. Achieving success with both types of scholarly writing largely depends on how well you manage your time and write academically.
