D)regression coefficient

Question

Quizplus · Accepted Answer

The coefficient of determination, also known as R-squared, measures the proportion of the total variation in the dependent variable that can be explained by the independent variable(s). It is a better measure of the strength of the relationship in a linear regression than just the correlation coefficient (A) or the regression coefficient (D), which only describe the direction and magnitude of the relationship, respectively. The linear coefficient (B) is not a commonly used term in regression analysis.
