Question

Quizplus · Accepted Answer

The group that drinks energy drinks is the experimental group, as they are being tested for the effect of the independent variable (energy drink consumption) on their dependent variable (calculus test scores). The control group would be the group that does not drink energy drinks, and serves as a comparison group for the experimental group. The terms primary and secondary are not relevant in this context.
