Given that the sum of squares for error is 60 and the sum of squares for regression is 140, then what is the value of the coefficient of determination?
A) 0.300
B) 0.429
C) 0.700
D) 0.837

Question

Quizplus · Accepted Answer

The coefficient of determination, R², is calculated as the sum of squares for regression divided by the total sum of squares (sum of squares for regression + sum of squares for error). Here, R² = 140 / (140 + 60) = 140 / 200 = 0.700.
