Pretend that I (your professor) have enough free time to create an elaborate database for one of my classes that contained the following information:

1) daily attendance

2) grades for every assignment and test (including date of assignment)

3) age of students

4) every contact that each student made with me including email and office visit

5) voluntary class participation per student

6) whether students were freshmen, sophomore, junior, or senior

7) how many hours each student worked at a job each week

What ways I (the professor) could examine the relationship of this data to learn more about this class. Also, is there any additional data that would be interesting to have to examine this class?

Example: "I would like to analyze the relationship between class attendance and grade. I suspect that, on average, the students who do not show up to class are less likely to perform well..."
