The percentage of total variation in the dependent variable that is described by the independent variable is the coefficient of determination, also known as R-squared. It is a measure of how well the regression line fits the observed data. The correlation coefficient measures the strength and direction of the linear relationship between two variables, but it does not provide any information about how much of the variation in the dependent variable can be explained by the independent variable. The coefficient of covariation is a measure of the relative variability of two variables, and the regression coefficient is the slope of the regression line.
