The Same or Not the Same: Equivalence as an Issue in Educational Research
Lewis, Scott E.; Lewis, Jennifer E.
Journal of Chemical Education, v82 n9 p1408-1412 Sep 2005
The commonly used method of reliance on failure to reject the conventional null hypothesis as a positive indication of equivalence is questioned in a study. An alternative method, based on a re-visioning of the null hypothesis, is proposed which also avoids the uncontrolled type II error present in the traditional method.
