Quizplus · Accepted Answer

A zero regression residual means that the actual value of the dependent variable is exactly what was predicted by the regression equation, indicating a perfect fit between the predicted and actual values. A negative correlation (option A) implies a non-zero residual, while options C and D describe scenarios where the residual is non-zero as well.
