Now we can simply divide the numerator (Metric 3) with the denominator (Metric 4) to get the skewness value. berikut : kurtosis x. (Wright & Herrington, 2011). These distributions have heavy tails that are longer and contain more extreme values. The kurtosis of the exam scores was found to be 4.17, indicating that the distribution was more heavy-tailed compared to the normal distribution. Acceptable range for normality is skewness lying between -1 to 1. Acceptable Range Of Skewness And Kurtosis For Normal Distribution Of Data. The values for asymmetry and kurtosis between -2 and +2 are considered acceptable in order to prove normal univariate distribution (George & Mallery, 2010). The "minus 3" at the end of this formula is often explained as a correction to make the kurtosis of the normal distribution equal to zero, as the kurtosis is 3 for a normal distribution. The values for asymmetry and kurtosis between -2 and +2 are considered acceptable in order to prove normal univariate distribution (George & Maller dari setiap batang pada dasar grafik adalah 10.

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. Values of skewness or kurtosis. Khan and Rayner (which is mentioned in the earlier answer) work with a family that allows some exploration of the impact of skewness and kurtosis, but they cannot avoid this issue, so their attempt to separate them severely limits the extent to which the effect of skewness can be explored.
