We know that the average and standard deviation of percent fat is respectively 31.06 and 9.54. With SPSS, for each event, we easily calculate the z scoresCI.[new min, new max] = [0 , 1] range.The values are forced to a certain set by using the min-max normalization. The benefit of this approach is the inclusion of outliers in the results.II.Z normalization is-classified, -listed, [[classified]. The values of v^'=(v-meam)/std are
