Fisher pearson skewness
WebExpert Answer. 1. One of the ways to measure skewness of a distribution is by using the Fisher-Pearson moment coefficient of skewness. The formula of Fisher-Pearson moment coefficient of skewness is E [ (X-μ)³] E (X³) - 3μσ² - μ³ 03 (0²)3/2 If the value is positive, it indicates skewed to the right. If the value is negative, it ...
