Quizplus · Accepted Answer

The coefficient of determination (r-squared) measures the proportion of the variance in the dependent variable that can be explained by the independent variable. A coefficient of determination of 0.94 means that 94% of the total variation in the dependent variable is explained by the independent variable. Therefore, the correct choice is C. Choices A and D are incorrect because the coefficient of determination does not indicate the strength or direction of the relationship between variables.
