Formula:

Skewness Coefficient = 3 x (mean - median) / σ Where, σ=Standard deviation.

Coefficient of Skewness: Skewness Coefficient also known as Pearson's Coefficient of Skewness or moment coefficient of skewness is the third standardized moment. It can be termed as Skew(X) and it is dependent on the mean, median and standard deviation of a given set of data.

Pearson's Coefficient of Skewness Calculator: Feel free to try this simple online skewness calculator to find the coefficient and other attributes of measure of central tendency. Just enter the set of values as comma separated data and click on calculate to get the result of Pearson's coefficient of skewness.

Example

For a given set of values 3,5,1,6,3

Mean = 3+5+1+6+3 / 5
        = 18 / 5
        = 3.6

Median = 3

Standard Deviation (σ) = [(3 - 3.6)2) + (5 - 3.6)2) + (1 - 3.6)2) + (6 - 3.6)2) + (3 - 3.6)2) ] / 5
= √(3.04)
σ = 1.7436

Pearson's Moment Coefficient of Skewness = 3 x (3.6 - 3) / 1.7436
Skewness Coefficient = 1.032
