1. A clinician investigated the effects of using a behavioral treatment to reduce the amount of foul language spoken by eight children living in a Group Home. The clinician measured the number of foul words spoken before treatment (baseline), 1-week after treatment, and 1-month after treatment by each child. The number of foul words spoken by each child during each of the three time periods is shown below.

	Time Period
Participant	Before Treatment	1-Week After Treatment	1-Month After Treatment
1	26	25	22
2	28	33	27
3	29	31	30
4	32	38	36
5	24	23	23
6	30	34	31
7	33	36	29
8	37	39	33

4. Usinga = .05, does it appear that the sphericity assumption was violated for these data (2 pts.)?
5. Using = .05, should we reject or retain the omnibus null hypothesis (2 pts.)?

1. What Bonferroni alpha level should be used to evaluate the significance of each post hoc test (2 pts.)? ___
2. Using _Bonferroni and the results of the appropriate post hoc tests, discuss each of the unique pairwise comparisons of foul language spoken during each time period (3 pts.).

a. Before vs. 1 Week After:

b. Before vs. 1 Month After

c. 1 Week After vs. 1 Month After:

Did the behavioral treatment reduce the amount of foul language used? What specifically did the results indicate in words (5 pts)? ______________________________________________________________________________________________________________________________________________________________________________
