The second quiz (see dates page) will cover the following material:

- Complete an incomplete ANOVA table and answer questions from it. This is similar to the One-Way ANOVA HW #1.
- Answer questions for an analysis of 1-Way ANOVA data that will require you to reference R output that will be provided. This will be most similar to One-Way ANOVA HW #4, but will have some parts of One-Way ANOVA HW #3. Here is an example from a previous year’s exam.
*Note that this is an example only; the actual question will be different than this one.* - Fully answer short-answer questions from among the following list.
- Completely compare and contrast the meanings of MS
_{Within}, MS_{Total}, and MS_{Among}. Consider all possible meanings for these terms. - Completely compare and contrast the concepts of a “full” and a “simple” model.
- Describe when a Tukey’s HSD and when a Dunnet’s procedure should be used. Describe why the Dunnet’s method is “better” than Tukey’s method if Tukey’s method was applied to the situation where the Dunnet’s method should be used.
- Describe why performing multiple individual 2-Sample t-Tests to determine which specific pairs of means differ is problematic.
- Define experiment-wise and comparison-wise error rates. Identify the specific and relative sizes of each error rate and specifically comment on what happens to each as the number of comparisons made increases.
- List the assumptions of a one-way ANOVA and thoroughly describe how you would test each one (describe hypotheses and tests for each as appropriate).
- Mathematically show that the difference in two means of a log-transformed variable becomes a RATIO of two means on the original scale. You do not need complete sentences for this question but you should mathematically show each step in the proof.

- Completely compare and contrast the meanings of MS

The quiz is closed book and closed notes, you will not need to use R (but will need to be able to interpret results provided from R), you should bring a calculator and a pencil (exams written in pen will not be accepted), and be prepared to write neatly.

Please let me know if you have any questions. Thanks.
