Final answer:
The control group is used for comparison in an experiment, not to test the independent variable; it helps ensure observed changes are due to the independent variable.
Step-by-step explanation:
The statement is false. In an experiment, the control group is not used to test the effect of the independent variable; instead, it is used as a basis for comparison with the experimental group, which is exposed to the independent variable.
The control group should be identical to the experimental group except for the introduction of the independent variable.
This way, researchers can measure the changes in the dependent variable that are caused by the independent variable within the experimental group. By having a control group, researchers can control for chance factors and ensure that any differences observed in the experiment are due to the manipulation of the independent variable and not other variables.
