  • To use , you first need to load the Hypothesis Testing Package using Needs["HypothesisTesting`"].
  • gives a -value for the test that the variance of the population from which list was sampled is significantly different from .
  • uses the test statistic , where var=Variance[list] and df=Length[list]-1.
  • is based on a distribution with Length[list]-1 degrees of freedom.
  • The following options can be given:
  • FullReportFalsewhether to include detailed information about a test
    SignificanceLevelNonesignificance level of the test
    TwoSidedFalsewhether to perform a two-sided test
  • With the option FullReport->True, also returns the sample variance, the test statistic, and the distribution used to generate the -value.
