Control Group doesn't receive any treament or a placebo or a treatment whose outcome is already known;
Treatment Group receives the treatment;

For the female mice on the image below, in the First Group is not injected any dosage of BPA, so they are the control group, while the others are treatment group.

The variables in a experiment are classified as independents or dependents:
