The coefficient of determination is more precise than using a correlation coefficient alone.

Question

Quizplus · Accepted Answer

The coefficient of determination, also known as R-squared, provides information about the proportion of variance in the dependent variable that is predicted by the independent variable(s). It is a more precise measure of the strength and direction of the relationship between variables than a correlation coefficient alone. A correlation coefficient only measures the strength and direction of the relationship between variables, but it does not provide information about how much of the variation in the dependent variable is explained by the independent variable(s).
