Suppose that a set of data has a perfect linear correlation except for two outliers, one above the line of best fit and the other an equal distance below it. The absolute value of the residual for these two outliers is equal. Would you agree that a perfect linear correlation exists because the effects of the two residuals cancel out? Support your opinion with appropriate mathematical reasoning from the unit.
