The figure below illustrates this: watch the histograms become “wider” as the variances increase. We therefore compute the absolute differences between all scores and their (group) means.

WebFeb 25, 2024 · This test statistic follows a Chi-Square distribution with k-1 degrees of freedom. That is, B ~ X 2 (k-1). If the p-value that corresponds to the test statistic is less than some significance level (like α = 0.05) then we can reject the null hypothesis and conclude that not all groups have the same variance. Example: Bartlett’s Test WebApr 23, 2014 at 19:59. 1. What you have there is a table of critical values.
