Answer 1

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

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

A <B>dependent variable</B> is the response or measure of results.

<B>Extraneous variables</B> — 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 <B>experimental group</B> receives the independent variable.

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