Best Answer: An independent variable is basically a variable that can be any number. The dependent variable is the variable calculated from the independent variable. For example, I do contract work where I get paid for every hour of work I do in a given week. If I work more hours, my paycheck is bigger.
In experimental studies, where the independent variables are imposed and manipulated, the dependent variable is the variable thought to be changed or influenced by the independent variable. Example: study title: Effects of a new tooth paste (YummyTooth) on incidence of caries in 1st grade children. is the independent variable and Y is the dependent variable-the outcome, and Z is the type of subjects represented. A simple example would be: The effects of tomatoes on risk of prostate cancer in Scandinavian men.
