Answer:
to compare the results when the independent variable is not involved
Explanation:
Dependent variable depends on the independent variable. Independent variable is the one that is being tested in a science experiment to test how it is affecting the dependent variable.
In a control group in an experimental investigation the independent variable is omitted. Thus the goal is to test if the dependent variable shows any change in the absence of the independent variable.
