A study was conducted which administered a memory enhancing drug (Four doses: (Placebo, Small, medium, Large dose) to younger (18-30) and older adults (65>). Half of the participants were male and half were female. All participants were given a word recall test and the number of words recalled are presented below.

1. Conduct the appropriate Gender x age x dose three factor anova and paste the results below.

1. Conduct the appropriate test for homogeneity of variance and paste the results below.

1. From the anova table fill in the appropriate number.

1. Average variance within the groups. ______
2. Denominator for all the F tests. _________
3. Variance among the dose main effect means.________
4. The variance among the 16 group means that remains after subtracting the variance due to the main effects and 2-way interactions. ____________
5. Compute a 2(Age) x (4Dose) just for females anova and paste the results below.(1=female, 2=male)

1. Compute a 2(Age) x (4Dose) just for males anova and paste the results below.(1=female, 2=male)
2. Calculate the appropriate F ratios below to test the significance of the Age x Dose interaction just for females and just for males. Replace the X with the appropriate MS values for each F.

F age x Dose (for females) =X/.194

F age x Dose (for males) =X/.194
