Country Differences

Different countries follow different structures for their education system. The definitions for academic terms are also different. This specifically stands for thesis vs dissertation concepts. It is more specifically different in the US and in Europe.

In Europe:

  • It is important for a doctorate program holder to submit a thesis.
  • On the other hand, a dissertation is a research project that is required for a Master’s degree program.

In the United States:

  • The definitions of thesis and dissertation are completely opposite to each other.
  • The thesis is a research project that is compulsory for the program of a master’s degree. On the other hand, a dissertation is compulsory for a doctoral degree.
  • So, the thesis will have the arguments from the existing research. While in the dissertation, students will choose a topic that has not been explored yet.

Type of Degree

The thesis vs dissertation is what in the terms they are specifically used for. The dissertation is required to get the highest degree in different fields.

The thesis is required to complete the master’s degree program. So students will have the second cycle qualification after that bachelor’s degree program by submitting their thesis.

There are also some cases where a thesis or dissertation is not required. As it completely depends on the type of degree and the institution from where the students are completing their degree.

Data Collection

Another important difference between dissertation and thesis is the data collection process in which the students go through. Apart from the differences, keep in mind that the purpose of both papers is the same.

Master thesis and doctoral dissertation need research conducted in an extensive way in order to prove that the students have gathered enough information on their field of study.

A dissertation is an original or genuine research required for students to graduate from a doctoral or Ph.d. degree program.

In most cases, it uses primary data.
