Skewness And Kurtosis Spss. If skewness is between 0 5 and 0 5 the distribution is approximately symmetric. Spss descriptive output showing skewness and kurtosis values for gpa and final the above descriptive statistics chart shows the data in terms of mean standard deviation skewness and kurtosis in relation to gpa and final with n 105 representing the sample size.
If skewness is between 1 and 0 5 or between 0 5 and 1 the distribution is moderately skewed. Notice that we define the excess kurtosis as kurtosis minus 3. The skewness statistic is 719 and kurtosis is 125 see above.
Here x is the sample mean.
N represents the number of observations. The kurtosis is negative with a value greater than 3. If skewness is between 0 5 and 0 5 the distribution is approximately symmetric. If skewness is between 1 and 0 5 or between 0 5 and 1 the distribution is moderately skewed.
