The skewness value can be either positive, negative or zero. 2) Kolmogorov-Smirnov test. So if you want to investigate the impact of high skewness, you are unable to avoid investigating the impact of high kurtosis. Skewness is a measurement of the symmetry of a distribution. Unlike test statistics from normality testing procedures like the Kolmogorov-Smirnov or the Shapiro-Wilk , skewness and kurrtosis are used here like an effect size, to communicate the The problem is that if you want to examine the effect of a highly skew distribution, you must also have a distribution with high kurtosis.
