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.
MORE INFORMATION
  • 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.
