Coefficient of skewness range
WebDec 15, 2014 · Hair et al. (2010) and Bryne (2010) argued that data is considered to be normal if Skewness is between ‐2 to +2 and Kurtosis is between ‐7 to +7. Multi-normality … WebSkewness = -0.39 Therefore, the skewness of the distribution is -0.39, which indicates that the data distribution is approximately symmetrical. Relevance and Uses of Skewness Formula As this article shows, one may use skewness to describe or estimate the symmetry of data distribution.
