Which research question would be most appropriate for a four- to five-page research paper? Are teens that play sports less likely to have jobs at the same time? Would cutting extracurricular activities anger students? Is there a correlation between extracurricular activities and grades? How many teens participate in extracurricular activities every year?
This seems kind of opinionated; however, I would go with the most vague, least specific question, because one could probably write more about that topic. So, "How many teens participate in extracurricular activities every year?" it is!
