An experiment is designed so you can observe the difference between the experimental group and the control group.
The experimental group is the group that receives the specific treatment or intervention being studied, while the control group is kept under normal or standard conditions and does not receive the treatment. By comparing the outcomes of the experimental group with the control group, researchers can observe and measure the difference in the results to determine the effectiveness of the treatment or intervention being tested.
Having a control group helps researchers reach accurate conclusions regarding the effects of the intervention under study by reducing the impact of confounding variables and establishing a baseline for comparison.
