• Calculating the F statistic (variation BETWEEN a group of means and WITHIN the groups)
• Null hypothesis: there is no significant difference between any of the groups
• Does not tell which groups are different

Question 2

What is the goal of a TSD post-hoc test?

Answer 2

To determine which groups are different in a single anova test

Question 3

How do we communicate statistical significance in a single factor anova graph?

Answer 3

Means that are not statistically significant share the same letter and unique letters represent significant means from each other
