Question

To estimate the accuracy of predicted values, Ў  , found in bivariate regression, it is useful to calculate the ________, the standard deviation of the actual Y values for the predicted  Ў values.  
A) standard error
B) covariance
C) coefficient of determination
D) standard error of the estimate

Quizplus · Accepted Answer

The standard error of the estimate measures the variability (standard deviation) of the errors (residuals) in predicting the Y values from the X variable in a regression equation. Therefore, it is the appropriate choice for estimating the accuracy of predicted values in bivariate regression.
