Statistics - Karl Pearson Method

There are certain ways to determine the skewness in data but on of the most effective way is the Karl Pearson method :-

                             Skewness = Mean -Mode

Coefficient of Skewness = Mean - Mode / Standard Deviation

In case where , we cannot determine Mode , then the formula will be like

Skewness = 3 Mean – (3 Median – 2 Mean) / SD

                   = 3 (Mean -Median ) / SD

Since our current formula is

3(Mean – Median) /Standard deviation is equal to Mean – Mode / SD

Then ,

                        3 Mean - 3 Median = Mean - Mode

                        Mode = Mean - 3 Mean + 3 Median

                        Mode = 3 Median - 2 Mean
