• ANOVA is about the mean and t-test is about the variance

What does ANOVA stand for?

Which is the correct order of steps for calculating and interpreting a one-way ANOVA?

• Determine SS, Calculate df, Calculate MS, Calculate F, Compare F obtained to F critical
• Calculate F, determine SSS, Calculate df, Compare F obtained to F critical
• Find F and compare
• Calculate T, calculate df, compare T obtained to T criitical

Using your F table, what is the critical value for a set of sample data that has a df between of 3 and a df within of 10?

• 3.86
• 3.71
• 6.61
• 5.41

Which group is causing the differences here?

• High Stress
• Moderate Stress
• Low Stress
• They all contribute equally
