Hypothesis Testing Package >

VarianceTest


performs a test with null hypothesis .
  • gives a p-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 p-value.
