1. Applying ANOVA Using brute-force, Excel and Minitab to perform ANOVA

2. Warm-up • Look at the following applet from the IPS website to remind you that ANOVA and F-scores investigate two sets of variances: • Variances between data sets • Variances within data sets

3. Example 12.21 (pg 786) • Graph data – use boxplots if you have a stats package • Prepare a table giving n, m and s for each group N1 = 19 N2 = 19 N3 = 8

4. Boxplot of data • Are the means different?

5. Example 12.23 (pg 787)
