Fisher's skew
WebFeb 12, 2024 · Skewness = [n/ (n-1) (n-2)] * Σ [ (xi–x)/s]3. where: n = sample size. Σ = fancy symbol that means “sum”. xi = the value of the ith value in the dataset. x = mean. s = standard deviation. The formula is a bit complex, but luckily Excel performs this calculation for you so that you don’t have to do it manually. 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.
