Tests for Standard Deviations (Two or More Samples)
support.minitab.comsample designs and k-sample designs with k > 2 as multiple-sample designs. Generally, these two types of designs are studied separately (see Appendix A). Because the standard deviation is the square root of the variance, a hypothesis test that compares standard deviations is equivalent to a hypothesis test that compares variances. Many
