A research team wants to see if youth participation in cultural and sports activities may be related to higher values of self-esteem. A group of 100 youths who do participate in such activities were found to have a mean self-esteem of 53.8 (with a standard deviation of 5.1). For the general population of youths, the mean score on the same self-esteem measure is 50, and the standard deviation is 5.9). Use this information to calculate and interpret the effect size for the mean difference between participating youths and the general youth population.
