The percentage of variation in one variable that can be predicted from the other variable increases as the magnitude of the correlation coefficient increases. Correlation coefficient measures the strength of the linear relationship between two variables. As the correlation becomes stronger, the amount of variability in one variable that can be explained by the other variable also increases.
