(1982). The mean and standard deviation used in this script are derived from a group of female college students (N = 140) zscore: the z-score of the EAT27 Total Score with mean = 9.9 and sd = 9.2 pvalue: the percentile of the EAT27 zscore ___________________________________________________________________________________________________________________ NORMS ___________________________________________________________________________________________________________________ Norms are calculated based on data published by Garner et al.
