The dependent variable is the variable that is being measured and is expected to change as a result of the independent variable. In this case, the independent variable is talking on a cell phone while driving and the dependent variable is the time it takes for the driver to react to unexpected events. The car and cell phone are not the variables being measured, and Madison is the researcher conducting the study, not the variable being measured.
