WebLevene’s Testing Procedure Step 0: Check the assumptions. Step 1: State the null and alternative hypotheses. Null H 0: σ 1 2 =σ 2 2 =L=σ t 2 Alternative H a: Not all of the variances are equal. Step 2: Decide on the significance level, α. α = _____ Step 3: Determine the critical value and rejection region. Classical Approach P-value Approach Critical Value: … WebThe sampling distribution of the test statistic is fairly robust, especially as sample size increases and more so if the sample sizes for all factor levels are equal. ...

If we only have summarized data (e.g. the sample sizes and sample variances or sample standard deviations), then the two variance test in Minitab will only provide an F-test. Minitab will use the Bonett and Levene test that are more robust tests when normality is not assumed. is the king james bible the true word of god
