Answer to Question 1

Visit the tutoring program on the first day. Follow these students and the students not in the program as they take the statistics course. At the end of the course, compare the grades of students who took the program with grades of those who didn't. Even better would be if you could randomly assign half of the students to participate in the tutoring program. This would turn the study into an experiment, instead of an observational study.

Answer to Question 2

Ask students whether or not they took the tutoring program. Compare the grades of students who took the program with grades of those who didn't. Confounding variables would be a problem in this study.
