The coefficient of determination is important in explaining variances in estimating equations.For a certain estimating equation,the unexplained variation was given as 22,506.The total variation was given as 51,150.What is the coefficient of determination for the equation?
A) 0.34
B) 0.43
C) 0.56
D) 0.75

Question

Quizplus · Accepted Answer

The coefficient of determination (R²) is calculated as 1 minus the ratio of unexplained variation to total variation. Here, R² = 1 - (22,506 / 51,150) = 0.56.
