In the representative study sample of n=100 adolescents with the history of group participation is given the standardized self-esteem problemnaire. For general population of adolescents, score on this problemnaire form normal distribution with mean of µ = 40 and standard deviation of σ =12. The sample of group participation adolescents had average of M = 43.84.
