Skewness

Skewness[list]

gives the coefficient of skewness for the elements in list.

Skewness[dist]

gives the coefficient of skewness for the symbolic distribution dist.

Details

  • Skewness measures the asymmetry in list or of dist.
  • A positive skewness indicates a distribution with a long right tail. A negative skewness indicates a distribution with a long left tail.
  • Skewness handles both numerical and symbolic data.
  • Skewness[{{x1,y1,},{x2,y2,},}] gives {Skewness[{x1,x2,}],Skewness[{y1,y2,}],}.
  • Skewness[] is equivalent to CentralMoment[,3]/CentralMoment[,2]3/2.
