Pearson's Skewness Coefficient is given BY

SKEWNESS: * Is measure of asymmetry of a probability distribution of a random variable * Measures of skewness: - - Pearson's mode or First Skewness coefficient = (Mean - Mode) /SD - - Pearson's median or second Skewness coefficient = 3 (Mean - Median) /SD - - Quaile skewness = ( Q3-2Q2 + Q1)/Q3 - Q1
