Webb25 jan. 2024 · Karl Pearson’s coefficient of skewness lies between -3 and +3. If SK = 0 then we can say that the frequency distribution is normal and symmetrical. If SK < 0 then we can say that the frequency distribution is negatively skewed. If SK > 0 then we can say that the frequency distribution is positively skewed. Example #1 Q.
