Since z-scores standardize different distributions for comparison by accounting for the mean and standard deviation of each distribution, two normal z-distributions plotted on the same graph will have the same relative frequency for each z-score. This is because z-scores are a way to describe the position of a raw score within a distribution in terms of how many standard deviations away from the mean it is.
