Quizplus · Accepted Answer

The second group is called the placebo control group because they receive a substance that looks and tastes like the supplement but has no active component. This allows for comparison with the experimental group (group 1) to determine if any observed effects are due to the active component of the supplement or simply the placebo effect. The third group is the true control group because they receive nothing at all, serving as a baseline comparison for the other two groups.
