... describes the difference between X and µ. Therefore, if a question asks you to calculate the z-score for a score that is above the mean by 4 points and has a standard deviation of σ = 2, you cannot calculate (X - µ) - - i.e., you cannot find the original values for X or µ and calculate the differenc ...
