Quartiles

Quartiles[list]
gives a list of the 1/4, 1/2, and 3/4 quantiles of the elements in list.
  • The second quartile is equivalent to Median[list].  »
  • For even Length[list], the first quartile is equivalent to the median of the smallest elements in list.
  • For odd Length[list], the first quartile is equivalent to the average of the median of the smallest elements and the median of the smallest elements in list.
  • The third quartile is defined as for the first, but with the largest rather than smallest elements.
