I’ll print the top 100 lines of age data from a survey on voters below: WebbWe can do just that by. first subtracting the mean over all scores from each individual score and. then dividing each remainder by the standard deviation over all scores. These two steps are the same as the following formula: Z x = X i − X ¯ S x. As shown by the table below, our 100 scores have a mean of 3.45 and a standard deviation of 1.70.
