control group

the group that does not receive the experimental treatment.

experimental group

In an experiment, the group that is exposed to the treatment, that is, to one version of the independent variable.

independent variable

variable that is manipulated

dependent variable

The outcome factor; the variable that may change in response to manipulations of the independent variable.

Theory
