Popular secondary data sources that you can use for your dissertation research


Data. If you are writing a thesis or doing scientific research, and you want to perform some type of statistical analysis, then you will need data to answer your research question. However, it’s not always obvious where you can find the right data for the job. Therefore, a question that I am often asked by students is: “Where can I find data for my thesis?”.

Project data
Search engines
Journal data
Researcher data

I’ll also share one of the most common questions I get asked on this topic: “Does this mean that a Master’s thesis is (much) longer than a Bachelor’s thesis?” Check out my answer to this question at the end of this post!

Books vs. articles

When they start their Master’s program, most students notice a transition when it comes to how ‘knowledge’ is transferred. Whereas most knowledge would come from books in their Bachelor’s program, suddenly academic literature such as scientific articles are dominant in the curriculum. Indeed, articles are a more advanced way of learning: whereas the author of a text-book has interpreted the findings of studies for you, with articles you have to now interpret the quality, merit and implications of this knowledge yourself!
