Quizplus · Accepted Answer

A residual is the difference between an observed value and the value predicted by a regression model. In this context, if a man has a residual of 10 pounds, it means his actual ideal weight is 10 pounds more than the predicted ideal weight, indicating that the predicted ideal weight is 10 pounds less than his stated ideal weight.
