Question: A behavior analysis would like to evaluate the effectiveness of a new technique for controlling classroom outbursts of unruly children. For a sample of n = 4 children the number of outbursts is recorded 1 day before the treatment, and again 1 week, 1 month and 6 months after treatment. Use Repeated measures ANOVA with $\alpha =0.05$ to determine whether there are significant changes in behavior over time
