You might find the citations on page 297 to be useful: I'd find the question most productive if it could be resolved into a statement such as "Skewness is so much more important to inferences than kurtosis that skewness at the level of ___ would typically distort results as much as would kurtosis at the level of ___." If skewness is less than -1 or greater than 1, the distribution is highly skewed. Type "2" first calculates the type-1 kurtosis, then adjusts the result: 0,41657.

I have just checked; The sample variance is now ok fully understood; I am now trying to calculate Kurtosis, allow me to share an example that draws my point of reference; Skewness: I think this comes from using your formula with the correct value of S. As I said, your formula is not the same as that used by SPSS; the fact that you previously got (using your formula with the wrong value of S) the same value as SPSS (to 2 sig figs at least) was a coincidence. Distributions with positive skewness have a longer tail to the right, those with negative skewness have a longer tail to the left. In addition, bivariate correlation analyses showed that NF was positively correlated with The results showed that these variables were normally distributed: All the absolute values of the skewness (ranges from -0.55 to 1.15) and kurtosis (ranges from -0.53 to 0.89) scores were smaller than 3 Type of algorithm for computing skewness.
