•3/23/2011 •1 Lecture 16: March 23, 2011 • Today: – Multiple Comparisons: middle page 450 - middle page 452 • Tukey’s Test: We’ll go through the five step in hypothesis testing. Well do this for all three (multiple!) comparisons. – Two-Factor ANOVA: pages 456-462 • A second “factor” is introduced to one-way (or one-factor) ANOVA • Connect Homework 10, tentative schedule: – I’m working on it. – It will be ready Thursday. – Two problems: ANOVA and then Tukey – It will be due Monday at 6:00 p.m. • Update to Worked-Out-Problems menu on my web site: – Problem 10.33, page 424 – Comparing Two Variances – Problem 11.1, page 464 – One-Way (One-Factor) ANOVA Go to Handouts menu on my web site and download: – F-table(.05) – Tukey table Discussion Session 9: Friday, March 25 First item of business: Go to the Handouts menu on my web site. Download the F-table(.05) and the Tukey table. Second item of business: Go to the Discussion-Data-Sets menu on my web site. Download the data set titled “Discussion 8 Data, ANOVA Problem 11.1, page 449.” This is an Excel spreadsheet that contains the data for Problem 11.1. I asked you to do this same thing for your last discussion on March 11. Third item of business: Convert the Excel spreadsheet to a Minitab spreadsheet. Use Minitab to run the ANOVA. Do you need directions regarding how to run Minitab ? Go to three Minitab slides near the end of Lecture 14 (March 9) or the same three slides near the beginning of Lecture 15 (March 21) to get the necessary information. Fourth item of business: Go to the Worked-Out-Problems menu on my web site. Click on Problem 11.1. The hypothesis-test steps are laid out for you, and the problem is solved. (These are the steps that we developed in Lecture 14 on March 9). Make the insertions required for Steps (2), (3), and (4) to confirm the final numbers obtained for MSA, MSE, and F. Fifth item of business: Do Problem 11.5 on page 452. This is aTukey hypothesis-test procedure for three paired differences. You will calculate the Tukey test statistic three times by hand: once each for pair (A,B), (A,C), and (B,C). We develop all of the steps and provide a complete example during Lecture 15 today March 23. “By hand” is not as involved as you may think.
