# QuartileSkewness

 QuartileSkewness[list]gives the coefficient of quartile skewness for the elements in list. QuartileSkewness[dist]gives the coefficient of quartile skewness for the symbolic distribution dist.
• A positive value of quartile skewness indicates the median is closer to the lower quartile than the upper quartile .
• A negative value of quartile skewness indicates the median is closer to the upper quartile.
