UAB-CORD SSI III Program Pre/Post Statistics for High School Students (N = 10). Students retrospectively recorded pre/post-participation ratings (0 = not at all, 1 = low, 2 = moderate and 3 = high) of their skills, abilities, interest, and confidence. The paired t test was used to test for pre/post mean differences at the 0.0500-level of significance with null hypothesis: difference = 0 and alternative hypothesis: difference <>0. Mean rating (), standard deviation (SD), matched pair dependent t-statistic (t), p-value (p), the correlation between the matched pair ratings (r), mean rating (), standard deviation (SD), matched pair dependent t-statistic (t), p-value (p), the correlation between the matched pair ratings (r), and effect size are displayed.
