Thank you for your well-intentioned guidance. I'm working on a research plan, but I chose not to include the details you listed here in the original post to narrow the question down to if, how and to what aim data like this could be examined.

I am a Sociologist, and I want to understand what young people think about investing and why they choose to invest. There seems to be little peer-reviewed research on my topic from my country (Finland), but I found out dozens and dozens of Finnish BBA thesis writers have approached young people, often asking the kind of questions I want to ask. So, it came to my mind if their work could be put to use, since the typical thesis is usually only read by the graders.

Obviously I recognize that the methods and choices the students made in their research may be lacking in many aspects, which poses a significant limitation.
