As you read the chapter, consider the following questions:
12.1 How do we test hypotheses about populations for three or more groups?
12.2 Why does ANOVA use variance instead of mean differences in its calculation?
12.3 What is an F ratio and how is it calculated?
12.4 How do between-groups and within-groups variance terms differ?
12.5 How do we use the F Table to conduct a one-way ANOVA?
