This is the third in series of tutorials on evidence-based practice (EBP). Previous tutorials can be found in the May 2002 and June 2002 issues of Perspectives on Language Learning and Education and on the Division 1 Web site. Tutorial #3 focuses on the second phase (Phase B) of Step #3— Identifying the Magnitude of the Effect.
The magnitude of effect helps clinicians determine the importance of the different scores for the experimental (treatment) and control groups. Magnitude goes beyond determining if there is a statistical difference; it allows clinicians to predict the likelihood that their client will benefit from a treatment. In addition, magnitude of effect metrics, in some cases, can be used to compare the outcomes of different studies to determine which is more likely to yield positive results.
