Hi,
Regarding the use of secondary data, it will depend on your institution policy, but in principle, the use of secondary data sources is considered appropriate for a Master dissertation.
Re the use of mixed-methods... I would not recommend them for a 3-4 months project, its time consuming and requires considerations in terms of both philosophical issues and matching of the qualitative and quantitative data (but check Abbas Tashakkori and Charles Teddlie books if you are considering it).
Finally, as bewildered says it is not as much what you do, but that you do it properly.
Best of luck!

Hi all,
I was wondering if anyone has been to/hear about the Gesis Summer school in statistical methods that takes place in Germany.
I am considering applying and would like to hear some opinions. e.g. what did you think about the courses/instructors? Were there enough opportunities for hands-on practice?

Thanks!!
