Quartiles

Quartiles[list]
gives a list of the 1/4, 1/2, and 3/4 quantiles of the elements in list.

Quartiles[dist]
gives a list of the 1/4, 1/2, and 3/4 quantiles of the symbolic distribution dist.

DetailsDetails

  • Quartiles[list] is equivalent to Quantile[list, {1/4, 1/2, 3/4}, {{1/2, 0}, {0, 1}}]. »
  • 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 like the first, but with the largest rather than smallest elements.
  • Quartiles works with SparseArray objects.
