A market research firm wants to pilot test children's toys in stores. They collect data on attitude ratings (higher scores reflect more liking) for three different toys and find the following results: Legos (M = 5.5; N = 10), a football (M = 4.5; N = 10), and a NERF gun (M = 6.0; N = 10). They also calculated the between-group and within-group sum of squares (SSB = 262.2; SSW =1220.4). Use a one-way ANOVA (where = .05) to determine if there are significant differences in children ratings of toys.

1. List your mean squares within groups

2. List your F statistic

3. List your critical F value

4. Are there statistically significant differences in ratings among different toys?

5. Calculate partial eta-squared for the effect of toy type on liking ratings

6. Calculate Turkeys HSD
