An independent variable is a treatment: something that is varied under your control to test the behavior of another variable.

A dependent variable is something that is measured in response to a treatment.

For example, you might want to test the ability of various promotions to enhance sales of a particular item.

In this case, the promotion is the independent variable and the sales of the item made as a result of the individual promotion is the dependent variable.
