This is followed by a manipulation of a given experience for one gro up while the other is not manipulated. One group is the experimental group that receives the manipulation. The other group is the control group that does not. The two groups are then compared to determine the influence of the manipulation.

"An exp eriment isolates and manipulates the independent variable to observe its effect on the dependent variable, and controls the environment in order that extraneous variables may be eliminated. Experiments establish cause and effect. A correlation identifies v ariables and looks for a relationship between them."
