Table 3 Metrics of the overall sample and 459 peer leaders chosen under various methods. The column of means and SD reflect values from all students in the study. For all other columns, displayed is the average score of peer leaders for each selection method in relation to their school-level mean value. Peer leader difference scores are presented in z-score units (number of standard deviations difference from the overall student population value). Bold values differ significantly from 0 at p < .05
