1.
Do the data meet criteria for homogeneity of variance? Provide a rationale for
your answer.

2.
If calculating by hand, draw the frequency distribution of the dependent
variable, hours worked at a job. What is the shape of the distribution? If
using SPSS, what is the result of the Shapiro-Wilk test of normality for the
dependent variable?

3.
What are the means for three groups’ hours worked on a job?

4.
What are the F value and the group and error df for this set of data?

5.
Is the F significant at ? = 0.05? Specify how you arrived at your answer.

6.
If using SPSS, what is the exact likelihood of obtaining an F value at least as
extreme as or as close to the one that was actually observed, assuming that the

7.
Which group worked the most weekly job hours post-treatment? Provide a
rationale for your answer.

8.
Write your interpretation of the results as you would in an APA-formatted
journal.

9.
Is there a difference in your final interpretation when comparing the results
of the LSD post hoc test versus Tukey HSD test? Provide a rationale for your
answer.

10.
If the researcher decided to combine the two Treatment as Usual groups to
represent an overall “Control” group, then there would be two groups to
compare: Supported Employment versus Control. What would be the appropriate
statistic to address the difference in hours worked between the two groups?
Provide a rationale for your answer.
