WebDec 14, 2014 · Skewness measures the lack of symmetry in a variable. The formula for the Fisher-Pearson skewness coefficient is: where , s, and n are the sample mean, the sample standard deviation, and the sample size, respectively. Note that in computing the skewness, the standard deviation is computed using n in the denominator rather than n - 1. WebMar 17, 2024 · The moment coefficient of skewness of a data set is skewness: g1 = m3 / m23/2 (1) where m3 = ∑ ( x − x̅) 3 / n and m2 = ∑ ( x − x̅) 2 / n x̅ is the mean and n is the sample size, as usual. m3 is called the third moment of the data set. m2 is the variance, the square of the standard deviation.
