Skewness And Kurtosis Spss. The kurtosis is positive with a value greater than 3. In spss the skewness and kurtosis statistic values should be less than 1 0 to be considered normal.
A measure of the peakedness or flatness of a distribution. 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 measures of the deviation from normality kurtosis. You can also see that spss has calculated the mean 46 93 metres and the standard deviation 21 122 metres.
Here x is the sample mean.
N represents the number of observations. The distribution has a lower and wider peak and thinner tails. The kurtosis is positive with a value greater than 3. If skewness is between 1 and 0 5 or between 0 5 and 1 the distribution is moderately skewed.
