In research design, the group that does not receive the treatment or intervention is referred to as the control group. This group serves as a baseline for comparison against the experimental group, which does receive the treatment. The control group is essential because it helps researchers isolate the effects of the treatment by controlling for other variables that might influence the outcome. By comparing the results of the control group with those of the experimental group, researchers can better understand whether any observed effects are due to the treatment or other factors. This setup is fundamental in scientific research to ensure the validity and reliability of the findings.
