Normality Test Spss Skewness Kurtosis. Those values might indicate that a variable may be non normal. You can also see that spss has calculated the mean 46 93 metres and the standard deviation 21 122 metres.
The skewness statistic is 719 and kurtosis is 125 see above. Here x is the sample mean. These often include the median standard deviation skewness and kurtosis.
While skewness and kurtosis quantify the amount of departure from normality one would want to know if the departure is statistically significant.
As with skewness a general guideline is that kurtosis within 1 of the normal distribution s kurtosis indicates sufficient normality. Clicking on options gives you the ability to select kurtosis and skewness in the options menu. Those values might indicate that a variable may be non normal. These often include the median standard deviation skewness and kurtosis.
