Title: Equivalence Testing: Where It’s Been, Where It’s At, and Most Importantly, Where It’s Going

Abstract: Equivalence testing emerged in Psychology around the mid-1990s as a method for detecting a lack of relationship among variables, even though the method has been popular in other fields (e.g., biopharmacology) for decades. To date, numerous tests have been developed for detecting the equivalence of independent means, a lack of correlation, the similarity of independent regression and correlation coefficients, etc., however there are still numerous possibilities for expanding the field in order to be able to test a wider a range of equivalence-based hypotheses. This talk will highlight current research on the multiplicity problem for one-way designs, one-way repeated measures designs and negligible interaction, in addition to proposing other possibilities for moving the field forward.
