Definitions:

Experimental Methods

Research designs involving the manipulation of variables to determine cause-and-effect relationships.

Nonexperimental Methods

Research designs that do not involve the manipulation of variables or random assignment of participants.

Randomization

Controlling for the effects of extraneous variables by ensuring that the variables operate in a manner determined entirely by chance.

Experimental Control

Eliminating the influence of an extraneous variable on the outcome of an experiment by keeping the variable constant in the experimental and control groups.
