Control Groups

A control group is a standard part of experiments used in research. It consists of subjects that do not receive the treatment or intervention being tested, allowing researchers to compare results against those who do. This helps determine if any observed effects are truly due to the treatment itself or other factors. For example, in a clinical trial for a new drug, one group might receive the drug (the experimental group) while the control group receives a placebo. This setup ensures that researchers can accurately assess the drug’s effectiveness.
