The standard error of estimate measures the variability of the actual scores around the predicted scores, while the standard deviation measures the variability of scores around the mean. Since X is helping to predict Y, the predicted scores for Y will be closer to the actual scores, resulting in a smaller standard error of estimate. The standard deviation is not directly affected by X, so its estimated value will remain unchanged. Therefore, the estimated standard error of estimate will be smaller than the estimated standard deviation when X helps to predict Y.
