Statistics

Executive Summary - 2003/04

The project involved student participants in 20 schools. These results are based on the 1184 (983 treatment, 201 control) students that had matched pretest/posttest scores. In this report the treatment students are considered in two groups depending on whether they attended public or Catholic schools. A 37-item questionnaire including three demographic items was administered before and after the treatment to both groups. Pretest/posttest gain scores for each item were compared by group and tested for significant (p< .05) differences using analysis of variance. These comparisons were followed up with an analysis by gender, to determine if the treatment was especially effective for young men or young women. Because three groups were compared, there are three pairs of comparisons: TCG – Public vs. Control, TCG – Catholic vs. Control and, TCG – Public vs. TCG – Catholic.
