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. What is the acceptable range of skewness and kurtosis for normal distribution of data? WebThe data which have high kurtosis value will have heavy tails and the kurtosis is known as leptokurtic kurtosis. "II" or "SPSS" or "SAS") or 3 (or "3", Type "2" first calculates the type-1 kurtosis, then adjusts the result: (or "1", "I" or "classic"), 2 (or "2", HWr6}WLmM'b8MQD}BlN !c- Measuring skewness and kurtosis.
