What defines a control group in testing?

Explanation:
A control group is a fundamental concept in experimental design, primarily used to establish a baseline for comparison. It consists of participants or subjects who do not receive the experimental treatment that is being studied. This allows researchers to isolate the effects of the treatment by comparing the outcomes of the control group to those of the experimental group, which does receive the intervention. By not being exposed to the experimental treatment, the control group helps to ensure that any observed effects are indeed due to the treatment and not other external factors. This comparative analysis provides insights into the effectiveness of the treatment and helps to draw valid conclusions about its impact. The other options refer to groups that either receive some form of treatment, which would not meet the definition of a control group, or are specifically involved in potentially biased scenarios (like solely receiving placebo effects) without maintaining the proper baseline needed for comparison. Therefore, the accurate definition of a control group lies in its role of not receiving the experimental treatment, allowing for a clear assessment of the treatment's effects in the study.
