Participants had a mean increase in their knowledge gain. The mean of the pre-test was 9.35 (sd =
3.354), and the mean of the post-test score was 14.36 (sd = 0.80). The range of the post-test score was
thirteen to fifteen out of fifteen. Interpret Significance. A paired-samples t-test was calculated to
compare the mean pre-test score to the mean post-test score. The mean on the pre-test was 9.36 (sd =
3.354), and the mean on the post-test score was 14.36 (sd = 0.80). The pre-test score range was 4-14,
and the post-test range was 13- 15. A significant increase from the pretest to the post-test was found (t
(10) = -5.142, p < 0.001).
