The residual for the point (15,80) is drawn on the scatterplot vertically as a yellow double-sided arrow to visually show the size of the residual. The mean square error is the variance of the residuals, if we take the square root of the MSE we find the standard deviation of the residuals, which is the standard error of estimate.
