130 observations generated by scores on a psychological test administered to Peru- vian teenagers (ages 15, 16, and 17). For each of these teenagers the gender (male = 1, female = 2) and socioeconomic status (low = 1, medium = 2) were also recorded. The scores were accumulated into five subscale scores labeled independence (indep), support (supp), benevolence (benev), conformity (conform), and leadership (leader).
