In the late 1930s and early 1940s an important sociology experiment took place in the Boston area. At that time 650 boys (median age = 10½ years) participated in the Cambridge-Somerville Youth Study (named for the two economically depressed communities where the boys lived).
The participants were randomly assigned to either a delinquency-prevention program or a control group. Boys in the delinquency-prevention program had a counselor and experienced several years of opportunities for enrichment. At the end of the study, police records were examined for evidence of delinquency among all 650 boys. Analyze the data in the table and write a conclusion.
