In a multiple regression analysis involving 15 independent variables and 200 observations, SST = 800 and SSE = 240. The coefficient of determination is ______.
A) .300
B) .192
C) .500
D) .700

Question

Quizplus · Accepted Answer

The coefficient of determination (R-squared) is calculated as:

R-squared = 1 - (SSE/SST)

Given that SSE = 240 and SST = 800, we can calculate R-squared as:

R-squared = 1 - (240/800) = 1 - 0.3 = 0.7

Therefore, the coefficient of determination is 0.7 or 70%. The best choice is D.
