Pearson's Coefficient of Skewness Calculator
English

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). It depends on the mean, median and standard deviation of a given set of data. Enter the data values into the calculator and you can find the skewness coefficient of the given data.

Formula:

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

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
