What is ANOVA?
How is it similar to T tests?
-performs 1 test (to see if the groups are different) across all groups, keeping alpha at .05
-both measure the difference between means and the amount of variability in each group
Explain the Family Wise Error Rate
-When you run multiple T tests with an alpha of .05, you increase the probability of making a type 1 error.
-alpha increases with each comparison (family wise error rate)
What does ANOVA do/consider?
1) Variability across all groups
-individual scores relative to overall mean (SStotal)
2) Variability between groups
-mean of each group relative to overall mean of all groups
3) Variability within each group
-SSerror
