An experimental group is a set of subjects in a scientific study that receives the treatment or intervention being tested. This group is compared to a control group, which does not receive the treatment, to determine the effects of the intervention. Researchers use the experimental group to observe changes and gather data related to the hypothesis being tested. In a typical experiment, such as those in psychology or medicine, the experimental group is crucial for understanding how a specific variable influences outcomes. By analyzing the results from the experimental group, scientists can draw conclusions about the effectiveness of the treatment or intervention being studied.
