Quizplus · Accepted Answer

The standard error of estimate is a measure of the degree of variability of the actual Y scores about the predicted Y scores. It measures the average distance that the observed values fall from the regression line. The other options, such as the standard deviation of the predicted Y scores or the standard deviation of the predictor scores, do not provide a direct measure of the degree of variability of the actual Y scores about the predicted Y scores.
