Abstract
Practitioners need to understand that statistically significant results are not necessarily evidence of effectiveness, and being evidence-based does not mean a program is guaranteed to work. Asking questions on the substantive importance, statistical significance, and effect size of the program are key when gathering evidence for program evaluations. Practitioners must remember that evidence should inform but never dictate the shape of policy and practice.
