WebMay 2, 2024 · Key Takeaways. Skewness is a statistical measure of the asymmetry of a probability distribution. It characterizes the extent to which the distribution of a set of values deviates from a normal distribution. Skewness between -0.5 and 0.5 is symmetrical. Kurtosis measures whether data is heavily left-tailed or right-tailed. WebMay 10, 2024 · 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 =.
