4. Childhood participation in sports, cultural groups, and youth groups appears to be related to improved self-esteem for adolescents (McGee, Williams, Howden-Charman, Martin, & Kawachi, 2006). In a representative study, a sample of n = 100 adoles- cents with a history of group participation is given a standardized self-esteem questionnaire. For the general population of adolescents, scores on this questionnaire form a normal distribution with a mean %3D %3D of µ = 50 and a standard deviation of o = 15. The %3D
