Normality Test Spss Skewness Kurtosis. It s absolutely symmetrical and. Clicking on options gives you the ability to select kurtosis and skewness in the options menu.
In spss the skewness and kurtosis statistic values should be less than 1 0 to be considered normal. So if we sample many values from such a distribution the resulting variable should have both skewness and kurtosis close to zero. Here x is the sample mean.
The skewness statistic is 719 and kurtosis is 125 see above.
Normality tests based on skewness and kurtosis. If skewness is between 0 5 and 0 5 the distribution is approximately symmetric. So if we sample many values from such a distribution the resulting variable should have both skewness and kurtosis close to zero. In both tests we start with the following hypotheses.
