Why is a control group needed in some statistical studies?
A control group is essential in statistical studies because it serves as a baseline for comparison against the experimental group. It helps isolate the effect of the treatment or intervention being tested by accounting for external variables that could influence the results. By comparing outcomes between the control and experimental groups, researchers can better determine whether observed effects are due to the intervention or other factors. This enhances the validity and reliability of the study's findings.
