Quizplus · Accepted Answer

The 0-mg condition represents the no-treatment control group, as they are not receiving any caffeine and are being used as a baseline comparison group to observe the effects of caffeine on anxiety levels in the other groups receiving 100 and 200 mg of caffeine. The experimental group is the group receiving the caffeine (100 and 200 mg), the manipulation check group is used to ensure the manipulation of the independent variable (caffeine) is successful, and the waiting-list control group is a type of control group used in studies with interventions that may require a waitlist period.
