VarianceTest[list, 02]
performs a test with null hypothesis 2=02.
  • VarianceTest[list, 02] gives a p-value for the test that the variance of the population from which list was sampled is significantly different from 02.
  • VarianceTest uses the test statistic df var/02, where var=Variance[list] and df=Length[list]-1.
  • VarianceTest is based on a 2 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, VarianceTest also returns the sample variance, the test statistic, and the distribution used to generate the p-value.
