Quizplus · Accepted Answer

A z-score for the mean in a normal distribution is always 0 because the z-score formula subtracts the mean from the given value and then divides by the standard deviation. Since the mean is already accounted for in the calculation of the z-score, the z-score for the mean is 0.
