1Proportions were compared at the School Level (N = 5), using Wilcoxon-Matched Pairs/Signed Rank Tests. P-values were identified as significant if they were less than or equal to .05, thus rejecting the null hypothesis (that the Intervention had No Effect); n.s. = not significant. 2There were 8 schools originally selected for this group; 1 school dropped out because they could not schedule the Intervention and another 2 schools were unable to schedule the Follow-Up (Delayed Post-Test) Survey, thus the data presented have complete information for each school at every measurement point. 3Percentages shown are the Medians, which summarize the distribution of correct responses by school. | |||||
