Calculating Mean ES Values for Expected Percent Reductions in Discipline Referrals and Approximating Power Using Statistical Power Curves

Expected Percent Reduction in Discipline Referrals	School #2 ES Value (17% Variability)	School #3 (37% Variability)	School #5 ES Value (9% Variability)	Mean ES Value (% Discipline Referral Reduction / % Variability)	Power
25 (low)	1.47	0.68	2.77	1.64	~ 0.45
35	2.06	0.95	3.89	2.30	~ 0.65
40	2.35	1.08	4.44	2.6	~ 0.8
45	2.65	1.22	5.00	2.96	< 0.8
75 (high)	4.41	2.03	8.33	4.9	< 0.8
