Dependent Variable
A dependent variable is the one which we can test in a scientific experiment, in order to get its values. The dependent variable is obviously ‘dependent’ on the independent variable.
Hence as the experimenter changes the independent variable, we can now observe and record the change in the dependent variable. So while taking data in an experiment, the dependent variable is the one being measured.
Dependent Variable Examples
A scientist is testing the effect of light and dark on the behavior of the moths by turning a light on and off. Here the independent variable is the amount of light and the moth’s reaction is the dependent variable.
A change in the independent variable i.e. amount of light directly causes a change in the dependent variable i.e. moth behavior.
