In Europe, a thesis is a requirement to graduate from a doctoral or Ph D 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.
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.
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.
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.
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.
