Answer

Brief Explanations:

A control group in an experiment has no changes to the independent variable. It serves as a baseline for comparison with the experimental group where the independent variable is manipulated. This helps in determining the true effect of the independent variable on the dependent variable.

Answer:

to compare the results when the independent variable is not involved
