Question

Quizplus · Accepted Answer

The coefficient of determination (r-squared) represents the proportion of variance in the dependent variable that is explained by the independent variable(s). Therefore, if the coefficient of determination is .09, it means that only 9% of the variance in the criterion is shared with the test variable. Therefore, the best answer is C) 9%.
