WebThe assumption of homogeneity of variance means that the level of variance for a particular variable is constant across the sample. If you’ve collected groups of data then this means that the variance of your outcome variable (s) should be the same in each of these groups (i.e. across schools, years, testing groups or predicted values). Web12 mei 2024 · The result is a test that is “conservative,” which means that it is less likely to commit a Type I Error, but this comes at the cost of less power to detect effects.
