Tests of Equivalence for One-Way Independent Groups Designs
Cribbie, Robert A.; Arpin-Cribbie, Chantal A.; Gruman, Jamie A.
Journal of Experimental Education, v78 n1 p1-13 2010
Researchers in education are often interested in determining whether independent groups are equivalent on a specific outcome. Equivalence tests for 2 independent populations have been widely discussed, whereas testing for equivalence with more than 2 independent groups has received little attention. The authors discuss alternatives for testing the equivalence of more than 2 independent populations, and they use a Monte Carlo study to demonstrate and compare the performance of these alternatives under several conditions. The results indicate that a 1-way test (e.g., Wellek's "F" test) is recommended for assessing the equivalence of more than 2 independent groups because approaches based on conducting pairwise tests of equivalence are overly conservative. (Contains 3 notes and 5 tables.)
