ANOVA Questions and Answers 2023-2024 Verified What is an ANOVA? ANOVA is an analysis of variance between groups (or levels of a factor) or within groups (or error) Whereas t-tests compare only two sample distributions, ANOVA is capable of comparing many. We partition the total variance into how group means differ from the grand mean and how individual observations within groups differ from their group's mean What are the three assumptions of ANOVA? 1. independence of observations 2. nor...
