WebJun 26, 2024 · A test shouldn't fail for an unrelated issue (i.e. not-included step). If you do come across something else though, then you need to find an applicable test that covers it and then fail that. However I agree it's possible you may find something that wouldn't be included in any test, so you may have to write a new very specific test for it. WebWhat is this test for? The one-way analysis of variance (ANOVA) is used to determine whether there are any statistically significant differences between the means of three or more independent (unrelated) groups.
