Complete the following exercises in your course text Using SPSS for Windows and Macintosh: Analyzing and Understanding Data, by Green and Salkind. Be sure to save your output and export it to your Word document, in which you also must answer the analysis questions and present your results section as indicated:

•Exercises 1–3 on page 137-138, One-way analysis of variance (ANOVA)
25.9: Alternative Analyses
Data for a one-way ANOVA can also be analyzed by using the Kruskal-Wallis nonparametric procedure (see K independent-¬samples tests in Lesson 43). If the assumptions of a one-way ANOVA are met, ANOVA is more powerful than the nonparametric alternatives. However, if the assumptions are not met, nonparametric alternatives may be more powerful.
Exercises: Lesson 25
The data for Exercises 1 through 3 are in the data set named Lesson 25 Exercise File 1. The data are from the ¬following research problem. (Please click link below)

Marvin is interested in whether blonds, brunets, and redheads differ with respect to their extrovertedness. He randomly samples 18 men from his local college campus: 6 blonds, 6 brunets, and 6 redheads. He then administers a measure of social extroversion to each individual.
1.Conduct a one-way ANOVA to investigate the ¬relationship between hair color and social ¬extroversion. Be sure to conduct appropriate post hoc tests. On the output, identify the following:
a.F ratio for the group effect
b.Sums of squares for the hair color effect
c.Mean for redheads
d.p value for the hair color effect

2.What is the effect size for the relationship between hair color and extroversion?
3.Create a boxplot to display the differences among the distributions for the three hair color groups.

•Exercises 5–8 on page 151, Two-way ANOVA
Exercises 5 through 8 are based on the following research problem. The data set for this problem is named Lesson 26 Exercise File 2 (Please click link below)

Vicki was interested in how much time fathers of children with a disability play with their children. To address this question, she found 60 fathers in six categories: (a) fathers with a boy with no physical or intellectual disability, (b) fathers with a girl with no physical or intellectual disability, (c) fathers with a boy with a physical disability, (d) fathers with a girl with a physical disability, (e) fathers with a boy with an intellectual disability, and (f) fathers with a girl with an intellectual disability. She asked fathers to record how many 10-minute segments per day they spent playing with their child for five days. The SPSS data file contains 60 cases and three variables, a factor indicating the disability status of the child, a factor indicating the child’s gender, and a play time score averaged across the five days.
5.Conduct a two-way ANOVA to evaluate differences among the groups, according to gender and disability status of the child, in the amount of time fathers spent playing with their children.
6.Which follow-up procedures should you use? Why?
7.Write a Results section reporting the results of the analysis.
8.Create a boxplot to show the distributions for the six groups.
