8.he most appropriate measure of the degree of variability of the actual Y-values relative to the estimated Y-values from a regression equation is the:

A)   coefficient of determination (R²).

B)   sum of squared errors (SSE).

C)   regression coefficient confidence interval (b₁).

D)   standard error of the estimate (SEE).

The correct answer was D)

The SEE is the standard deviation of the error terms in the regression, and is an indicator of the strength of the relationship between the dependent and independent variables. The SEE will be low if the relationship is strong, and conversely will be high if the relationship is weak.
