I am to do a project for an inferential statistics class and I would like some basic guidance.  I am to propose a research question. My proposed research question is "Does drinking stimulants such as coffee improve a student's grades?" My question is what do you think the best population for such a question would be if I am strictly doing research off of the internet? What do you think the variables would be? What method of sampling do you think would be best to incorporate?
