In a multiple regression analysis involving 10 independent variables and 81 observations, SST = 120 and SSE = 42.The multiple coefficient of determination is
A) .81.
B) .11.
C) .35.
D) .65.

Question

Quizplus · Accepted Answer

The multiple coefficient of determination (R-squared) is calculated as 1 - (SSE/SST). 
In this case, SSE = 42 and SST = 120, so R-squared = 1 - (42/120) = 0.65. 
Therefore, the best choice is D.
