Hi, Jimmy. Here is the same info as in your other thread. My advice is take a good book on research methods in social sciences and read carefully purposes of each research method. In brief, it all depends on what you are going to study and how far you will go. If it's something that hasn't been explored before at all, then qualitative research is more appropriate (interviews, observations, etc.). If you just want to compare something, look at an issue from a different angel, or test some hypothesis, use quantative methods (questionnaires, or other).
