What Is an Dependant Variable in a Scientific Experiment


The dependent variable is the one you change or test.

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.

For example, 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).

If the dependent and independent variables are plotted on a graph, the x-axis would be the independent variable and the y-axis would be the dependent variable.
