Explain the general rationale behind using a z-score for describing how an indivdual performed on an exam compared to just stating the overall mean and the indivdual's score. how does the information differ in the two situations? what additional information are you gaining with a z-score?

The z-score normalizes random variables to have a mean of zero and a standard deviation of 1. This allows you to directly compare any random numbers regardless of range. It then represents whether the random variable is above or below the mean and if it it way beyond central tendency given by the z-score, which indicates the number of standard deviations from 0.
