is an option to hypothesis test functions that specifies whether the test should be twosided.


  • To use TwoSided, you first need to load the Hypothesis Testing Package using Needs["HypothesisTesting`"].
  • With default setting TwoSided->False, the value is associated with the smaller tail of the distribution of the test statistics.
  • With TwoSided->True, the value is split between the two tails of the distribution of the test statistic.
