Study Design

An observational study finds that students who drink coffee score
higher on exams. No one was randomly assigned to drink coffee. What
can be concluded?

Drinking coffee causes higher exam scores.

Coffee drinking is associated with higher scores, but a
confounder (such as study habits) could explain both.

Coffee drinking has no relationship to exam scores.

Higher exam scores cause students to drink coffee.
