Question

Quizplus · Accepted Answer

The experimental group is the group that is receiving the treatment or intervention being studied, in this case, the group that ingests caffeine (coffee) prior to the exam. The group that drinks water is the control group, which is used as a baseline comparison for the experimental group. The performance on the exam is the dependent variable being measured, not the experimental group. There is no indication in the question that this is a case study, as an experiment is being conducted with a control and experimental group.
