    The percent of the variation in the dependent variable that can be explained by the independent variable is called coefficient of determination, which is r^2. In this case, r = 0.456. So r^2 = 0.456^2 = 0.208. That means 20.8% of the variation in the amount of money earned can be explained by differences in the number of hours worked.
