For a multiple regression model, SSR = 600 and SSE = 200. The multiple coefficient of determination is
A)0.333
B)0.275
C)0.300
D)0.75

Question

Quizplus · Accepted Answer

The multiple coefficient of determination is the ratio of the explained variance to the total variance. The total variance is the sum of the explained variance (SSR) and the unexplained variance (SSE). Therefore, the multiple coefficient of determination (R-squared) is: 
R-squared = SSR / (SSR + SSE) = 600 / (600 + 200) = 0.75

Thus, the best choice is D.
