The test calculates whether the sample variances are close enough to 1, given their respective degrees of freedom. For example, say we had two samples: n1 = 25, s1 = , and n2 = 36, s2 = s s FSTAT The degrees of freedom are v2 = 36 – 1 = 35 and v1 = 25 – 1 = 24 for the larger and smaller variances respectively. Mar 31, · Test for equal variances. Then run One-Way ANOVA using the new column as the Response. The F statistic and p-value will be the test statistic and p-value for Levenes test. For an example, see the link, Calculating Levenes Test Using Oneway ANOVA, below. Minitab offers several methods to test for equal variances. Consult Minitab Help to decide which method to use based on the type of data you have. You can also use the Minitab Assistant to check this assumption for you.

Use a test for equal variances to test the equality of variances between populations or factor levels. Many statistical procedures, such as analysis of variance. Levene's Test is a hypothesis test that determines whether a statistically significant difference In The Menu Click Stat > ANOVA > Test for Equal Variances >. How to interpret results from MiniTab's Test for Equal Variance.Levene’s Test is a hypothesis test that determines whether a statistically significant difference exists between the variance of two or more independent sets of non-normally distributed continuous data. It is useful for determining if a particular strata or group could . Learn more about Minitab Use a test for equal variances to test the equality of variances between populations or factor levels. Many statistical procedures, such as analysis of variance (ANOVA) and regression, assume that although different samples can come from populations with different means, they have the same variance. Mar 31, · Test for equal variances. Then run One-Way ANOVA using the new column as the Response. The F statistic and p-value will be the test statistic and p-value for Levenes test.

Consult Minitab Help to decide which method to use based on the type of data you have. You can also use the Minitab Assistant to check this assumption for you. P-value for the test. If there are 2 samples in the design, then Minitab calculates the p-value for the multiple comparisons test using Bonett's method for a 2 variances test and a hypothesized ratio, Ρo, of 1. If there are k > 2 samples in the design, then let Pi j be the p-value of the test for any pair (i, j . Open the Test for Equal Variances dialog box. Mac: Statistics > ANOVA > Equal Variances; PC: STATISTICS > ANOVA > Equal Variances; Select Responses are in one column for all factor levels. In Response, enter Correction Time.
