"child's choice of college" is the "dependent variable" in joanna's project.
A variable is any factor, attribute, or condition that can exist in varying sums or sorts. An examination for the most part has three sorts of variables: independent, dependent, and controlled.
A dependent variable is the thing that you measure in the analysis and what is influenced amid the examination. The dependent variable reacts to the independent variable. It is called dependent since it "depends" on the independent variable. In a logical investigation, you can't have a dependent variable without an independent variable.
