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

The standard error of the estimate is the measure of how well the regression line fits the data points. It estimates the average distance between the actual Y values and the predicted Ŷ values. Therefore, it is a good measure of the accuracy of predicted values. The coefficient of determination measures the proportion of the variation in Y that can be explained by the regression model and is not a measure of the accuracy of predicted values. The covariance and standard error are not directly related to the accuracy of predicted values in bivariate regression.
