Here is some information that should help you to decide.
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.
I hope this helps. Thanks for asking.
