The effects not directly related … WebHomoscedasticity, or homogeneity of variances, is an assumption of equal or similar variances in different groups being compared. This is an important assumption of parametric statistical tests because they are sensitive to any dissimilarities. Uneven variances in samples result in biased and skewed test results.
Web14 jul. 2024 · If we look at the output, we see that the test is non-significant (F 2,15 =1.47,p=.26), so it looks like the homogeneity of variance assumption is fine. Remember, although R reports the test statistic as an F-value, it could equally be called W, in which case you’d just write W 2,15 =1.47.
