Childhood participants in sports, cultural groups, and youth groups appear to be related to improved self-esteem (McGee et al., 2006). In a representative study, a sample of n = 100 participants is given a standardized self-esteem questionnaire. For the general population of adolescents, scores on this questionnaire form a normal distribution with a mean, µ = 50 and standard deviation, s = 15. The sample of adolescent participants had an average of M = 53.8. What is the effect size Cohen’s d and what does it tell us about the effect? 2. Compute the z-statistic.
