Medicine A will reduce the incidence of headaches . what is the independent variable and dependent variable and the two controlled variables?
Answered by PsyDAG
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.

From this information, you should be able to determine the independent and dependent variables. You have not mentioned any other variables that might need to be controlled. However, gender and age might fit.
