When setting up an experiment, it is necessary to have a control group TO COMPARE to the experimental group.

A control group is a group of individuals/subjects that are used to make comparisons in an experiment. This group (control group) does not receive the experimental treatment.

The control group closely resembles the experimental group that receives a given treatment.

However, since the control group does not receive the treatment, any difference with the 'target' experimental group is caused by the variable being tested.
