A professor at the University of Idaho was interested in studying the relationship between training for judges and offender participation in treatment programs. The researcher was interested in evaluating if training and follow-up increase the number of sessions an offender completed. The researcher randomly assigned 10 offenders to three conditions and then gathered information on how many sessions each person attended. The data is presented below.

Control group: 1, 2, 1

Training group: 3, 4, 3

Training and follow-up group: 7, 8, 9, 5

Using the information above completed Table 1 and Table 2 and answer the questions below.

Question
Using an alpha level of 0.05 and the four steps of the hypothesis testing process, test the research hypothesis that training increased participation in treatment.
Step 1
Step 2
Step 3
Step 4
Compute the effect size for training on participation in treatment?
Does this data meet the assumption of homogeneity?
