Question

What is the quartile skewness coefficient?

Answer 1

Determine the quartile skewness coefficient.

Bowley's skewness is another name for the quartile skewness coefficient. The skewness is determined by dividing the difference between the upper and lower quartile lengths by the interquartile range length.
Bowley's skewness is calculated using the following formula:

$\frac{Q_3+Q_1-2Q_2}{Q_3-Q_1}$

Hence, the required quartile skewness coefficient is $\frac{Q_3+Q_1-2Q_2}{Q_3-Q_1}$.
