A social psychologist is working with a child psychologist to study the effects of different behavioral interventions on aggressive behavior in children. They randomly select twenty-five children. Each child is observed by a "blind" observer who counts the number of aggressive acts committed by the child. For three weeks, aggressive behavior by all children is ignored by the psychologist (Extinction). For three weeks, aggressive behavior results in a time-out of two minutes (Time-out). For three weeks, aggressive behavior is ignored and non-aggressive behavior is rewarded with praise (Differential reinforcement). Order of treatment is varied. The data are ranks of each child at the end of each three-week period. The researchers are interested in whether type of behavior treatment has an
effect on aggressive behavior. What non-parametric test would you choose to answer the question?
