In experimental research, the control group serves as a baseline or standard for comparison against the experimental group.
The control group is not exposed to the experimental treatment or variable being tested, allowing researchers to isolate the effects of the treatment.
By comparing the results of the experimental group to the control group, researchers can determine if the treatment had a significant effect.
The control group helps to ensure that any observed changes in the experimental group are due to the treatment and not other factors.
This comparison is crucial for validating the results and drawing accurate conclusions from the experiment.
