Bartlett’s test is used to test if samples are from populations with equal variances. Some statistical tests, like the One-Way ANOVA, assume that variances are equal across samples. Bartlett’s test can be used to verify that assumption.
To conduct a Bartlett’s test for up to five samples, simply enter the data values below and click the “Calculate” button. A test statistic and corresponding p-value will be shown below. A p-value less than 0.05 is strong evidence that the variances are not equal across the samples.
