Definition of Dependent Variable

By

Definition: A dependent variable is the variable being tested in a scientific experiment.

The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the change in the dependent variable is observed and recorded.
Common Misspellings: dependant variable
Examples:
A scientist is testing the effect of light and dark on the behavior of moths by turning a light on and off. The independent variable is the amount of light and the moth's reaction is the dependent variable.

A change in the independent variable (amount of light) directly causes a change in the dependent variable (moth behavior).
