This statement is true as r, the correlation coefficient, measures the strength and direction of the linear relationship between two variables, and it can be expressed as the ratio of the covariance between the variables to the product of their standard deviations. Therefore, it can also be used to describe the proportion of variation in one variable that is explained by the other variable, and it can be expressed in terms of the decomposition of the total variation.
