In a multiple regression analysis involving 5 independent variables and 30 observations, SSR = 380 and SSE = 45. The multiple coefficient of determination is
A) .80.
B) .89.
C) .25.
D) .11.

Question

Quizplus · Accepted Answer

The multiple coefficient of determination is calculated as R^2 = SSR/SST, where SST = SSR + SSE.
Therefore, SST = 380 + 45 = 425.
R^2 = 380/425 = 0.894 which is approximately 0.89. So, the best choice is (B).
