A control group in an experiment is a group that does not receive the treatment or intervention being studied. It is used as a comparison to the experimental group to determine the effectiveness of the treatment.
Examples of control groups in experiments include: 1. In a study testing the effectiveness of a new medication, the control group would receive a placebo (a sugar pill) instead of the actual medication. 2. In a study examining the impact of a new teaching method on student performance, the control group would receive traditional teaching methods while the experimental group receives the new method. 3. In a study investigating the effects of a new diet on weight loss, the control group would follow their usual diet while the experimental group follows the new diet plan.
