As an alternative method of evaluating a group home, suppose that we take 12 adolescents who have been declared delinquent. We take the number of days truant (1) during the month before they are placed in the home, (2) during the month they live in the home, and (3) during the month after they leave the home.

The data follow:

Adolescent: 1 2 3 4 5 6 7 8 9 10 11 12 Before: 10 12 12 19 5 13 20 8 12 10 8 18 During: 5 8 13 10 10 8 16 4 14 3 3 16 After: 8 7 10 12 8 7 12 5 9 5 3 2 Apply Friedman’s test. What do you conclude?
