Indicate your subject in the "School Subject" box, so those with expertise in the area will respond to the question.

An **independent variable** is the potential stimulus or cause, usually directly manipulated by the experimenter, so it could also be called a manipulative variable.

A **dependent variable** is the response or measure of results.

**Extraneous variables** — other than the independent variable — potentially can affect the dependent variable, so they must be controlled. If possible, you try to keep them constant between the experimental and control group.

The **experimental group** receives the independent variable.

The **control group** is similar to experimental, except it does not receive the independent variable. Extraneous variables are balanced between experimental and control groups.
