A friend's assignment question is "Does class attendance affect GPA?"
She has 3 survey questions:
- How many courses do you have a week?
- How many classes did you miss a week?
- What is your GPA?
She is now told to analyse her data: her assignment question told her to analyse by combining two of the questions, but in her case, I told her she would need to use all three.
I was thinking of doing (percentage of class missed, (class missed/class taken a w/) compared to GPA.
She thinks she can just do classes missed compared to GPA. I told her this wouldn't work because someone could attend 3/3 of their classes, while someone else can attend 3/5 of their classes, and it wouldn't be well represented.
Could someone give some insight on the best method to represent the data to graph?
