There are several formulas to measure skewness. One of the simplest is Pearson’s median skewness. It takes advantage of the fact that the mean and median are unequal in a skewed distribution. Pearson’s median skewness tells you how many standard deviationsseparate the mean and median. Real … See more When a distribution has zero skew, it is symmetrical.
