Kurtosis meaning that the distribution is slightly flatter than normal or platykurtik. If you need to use skewness and kurtosis values to determine normality rather the Shapiro-Wilk test you will find these in our enhanced testing for normality guide. SPSS computes SE for the mean the kurtosis and the skewness A small value indicates a greater stability or smaller sampling err Measures of the shape of the distribution.
