1. Calculating Effect Sizes for Single Subject Designs 10.1

2. Classes of Effect Size Formulae Percentage of Non-Overlapping Data (PND) Identify the lowest baseline point Count the number of non-overlapping intervention points Calculate the proportion of non-overlapping to total number of intervention points (can’t use if baseline has a zero point)

3. PND = 8/10 = 80%

4. Classes of Effect Size Formulae Standard Mean Difference Subtract the mean of the baseline phase from the mean of the intervention phase Divided by standard deviation of baseline

5. SMD all = 7.23SMD 3 = 8.25

7. Classes of Effect Size Formulae Percentage Reduction (mean baseline reduction) Subtract the average of last 3 Tx points from the average of the last 3 baseline points Divide by the average of the last 3 baseline points Multiply by 100 for percent of baseline reduction

8. MBR=339.00

9. Classes of Effect Size Formulae Regression Models Regression equation obtained for baseline Regression equation obtained for Tx data Tx substracted from baseline and divided by standard deviation of baseline
