Dependent Variable 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.
A dependent variable is a variable whose value depends upon independent variable s. The dependent variable is what is being measured in an experiment or evaluated in a mathematical equation. The dependent variable is sometimes called the outcome variable.. In a simple mathematical equation, for example: a = b/c. the dependent variable, a, is determined by the values of b and c.
