Dissertation vs. Thesis | What Is the Difference? (2023)

You have to defend your dissertation or thesis to graduate from your university. No one ever said that getting an education would be easy. Obtaining a degree is even more challenging. Final qualifying work must show your readiness for independent professional activity. But which one to choose – thesis or dissertation? Read on this blog post aboutdissertation help to find out the significant differences between these two final works. We have described in detail the peculiarities down below!

Dissertation vs. Thesis

So what is the difference between dissertation vs. thesis? Many students ask this question in their final years of study. Some universities treat them both as identical, but there are several distinct peculiarities you should keep in mind. But first, let's look closer at the essential differences between these two works.

Thesis and Dissertation Have Different Degree Levels

Degree level is one of the key differences between these two types of works. There are three levels when you are asked towrite research:

  • Bachelor
  • Master
  • Ph.D.

Typically, you will need to present athesisfor a bachelor's and master's program. Meanwhile, Doctorate degrees are only awarded to those students who defend their dissertation.

Study Samples are Various for Thesis and Dissertation

As in any research paper, you should test ahypothesisor method that's called empirical research. For that, you should analyze data and results. Your bachelor's or master's paper should cover a sample of 30-40 applicants. But your doctoral research should provide answers to 100 people and more. Figuratively speaking, in the first case, you should study the group-level sample. In the second one, you should claim the whole region or population group. For example, you may explore all countries, all sellers from separate countries, or all 9th-grade students.

Thesis and Dissertation are Different in Volume

Both thesis and dissertation require a massive amount of effort. Unlike other types of academic projects, these ones have probably the bulkiest number of pages. Perhaps that's the main reason why most senior-year students prefer gettingthesis writing help. For Bachelor's or Master's work, it is enough to prepare material of around 100 printed text pages. Ph.D. students should prepare longer layers of work for at least 150 to 300 pages.

Sources Variation between Thesis and Dissertation

Your scientific work should be based on a list of sources mentioned in the body and conclusion thesis. This requires you tochoose a specific dissertation topicand rely on references that cover them in detail. In this writing assignment, applying theoretical knowledge is optional, and you may skip this part. When preparing it, you should process up to 50 scientific sources.

In dissertations, students should present an authentic idea that hasn't been researched before. You should conduct in-depth topic research and study it from different angles. Since your doctorate work is more comprehensive, you should add a practical part that is backed up by existing theories. You may even want to design atheoretical frameworkthat will keep you on track. Besides, you should design a much more extensive list that will include around 200 or even 300 books.

Originality Is Different in Thesis and Dissertation

Both thesis and dissertation have to be original in content. It means your work should have unique features that are not present in other studies. Less critical work requires a lower percentage of uniqueness is allowed. An indicator of work's originality reflects your own text to the actual work's volume. The uniqueness ratio depends on each schools' requirements. If 65-75% can be sufficient for theses, then Ph. D. works must be 90% authentic. It's a tough challenge to write so much unique academic content. Nevertheless, with athesis helper on your side, this will be much easier.

Thesis and Dissertation Have Slightly Altered Structural Elements

A practical dissertation writing part is necessarily included in dissertations. A conclusion should be followed after each chapter. In your thesis, you should emphasize all valuable outcomes of your study but not empirical components. Results serve as summaries and are placed once in the last part. In case you find anything of what we've just said difficult, ourPhD dissertation writing service is there for you 24/7.

Bottom Line

Let's sum up all the main differences between thesis vs dissertation. Basically, students present theses at the end of their bachelor's or master's degrees. While dissertations should be defended at the end of Ph.D. In the first case, you should just synthesize existing literature. But in the second one, you should conduct thorough research, introduce your own contribution (a.k.a. practical part), and add it to the present literature background.

Hi to all students and teachers. I have already written my master's thesis a few years ago and now I guess it's time to finally think about my dissertation. While reading this article, I started thinking about one question. How difficult is doctoral dissertation as compared to masters thesis?

Hi Boris,

Basically, both dissertation and masters thesis are sometimes treated as identical, but there are several distinct features. The dissertation requires a much deeper level of research than a senior thesis. The main difference is that dissertation typically requires bringing something new to the body of knowledge, adding a completely original and new research, while a master's thesis is mostly about collecting, reusing, and summarizing knowledge that already exists. Of course, it's all individual and depends on many different factors, but statistically a dissertation is more difficult to write than a master's thesis.

Idk why, but in my case writing a dissertation was easier. Maybe it's because I was going through a hard time in my life when writing my thesis, or the topic was harder itself and that's why it seemed more difficult. So yeah, it's all individual and a lot depends on your mood, environment, topic, productivity, and so on.

Hi Jane,

Absolutely agree with you. Writing your dissertation could also be easier because of the experience you gained while writing your previous assignments. Master's thesis is a complex paper that requires a lot of time and effort. By the time you wrote your dissertation, you already knew how to deal with advanced-level assignments like your senior thesis, so it was less complicated for you to write another difficult scientific paper. Anyway, best wishes in your further academic pursuits!

Yes, so true, I was really more prepared and experienced before writing my dissertation. Thanks!

Hi studycrumb! I am writing my dissertation and want to speak out. I am so mad because my dissertation supervisor is awful. She never gives good advice and is always biased. I feel so down and disappointed. What should I do?

Hi Tessa,

We are so sad to hear about your situation. A good and caring dissertation supervisor is a crucial aspect of a successful dissertation. So we can tell you one thing: if you feel like your dissertation supervisor isn't right, request to swap to someone else. If they are biased, mean, indifferent, useless, or you just don't like them for some reason, you have every right to change them! Remember that your choice and opinion should be respected and valued. Find an advisor who will be approachable, reliable, reassuring, give detailed feedback, and don't mind the odd panicked email. They are your lifeline and your best chance of success. Hope to hear from you again about your success in this issue! Good luck!

Thank you so much for your care and support, this means a lot to me! I will follow your advice and request to change my dissertation supervisor, and report back here about the result. Thanks!
