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.
