  • EqualVariances is an option for confidence interval and hypothesis test functions of two lists.
  • With the default setting EqualVariances->False, variances are estimated from the two samples independently if the variances are not specified as known.
  • With EqualVariances->True, a common pooled estimate of the variance is used for both populations if the variances are not specified as known.
