1. ANOVA: Why is it called “analysis of variance” when means are being compared?

2. ANOVA family
Statistic’s name “Groups” DVs (which means are calculated for the groups)
t-test one IV (binomial) one DV (I/R)
F-test one IV (nominal) one DV (I/R)
Two-way ANOVA two IVs (nom) one DV (I/R)
Multiple-factor ANOVA two+ IVs (nom) one DV (I/R)
MANOVA two+ IVs (nom) two+ DVs (I/R)
ANCOVA two+ IVs (nom) one DV (I/R) one+ covariates (controls)
MANCOVA two+ IVs (nom) two+ DVs (I/R) one+ covariates (controls)

3. ANOVA
Again, why is it called “analysis of variance” when it’s the means that are being compared across groups?

4. Mean = 30
Mean = 50

5. Mean = 30
Mean = 50
