In a regression analysis if SSE = 200 and SSR = 300, then the coefficient of determination is
A)0.6667
B)0.6000
C)0.4000
D)1.5000

Question

Quizplus · Accepted Answer

The coefficient of determination, denoted as R-squared, is calculated as the ratio of SSR to SST, where SST is the total sum of squares. SST = SSE + SSR. Therefore, 
SST = 200 + 300 = 500
R-squared = SSR/SST = 300/500 = 0.6. 
Hence the answer is option B.
