In a multiple regression analysis involving 15 independent variables and 200 observations, SST = 800 and SSE = 240. The coefficient of determination is
A)0.300
B)0.192
C)0.500
D)0.700

Question

Quizplus · Accepted Answer

The coefficient of determination (R-squared) is the proportion of the total variation in the dependent variable (SST) that is explained by the independent variables in the model. It is calculated as:

R-squared = 1 - (SSE/SST)

Plugging in the values, we get:

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

Therefore, the answer is D) 0.700.
