The Use of Equivalence Testing in Conjunction with Standard Hypothesis Testing and Effect Sizes.
Mecklin, Christopher J.
Whether one should use null hypothesis testing, confidence intervals, and/or effect sizes is a source of continuing controversy in educational research. An alternative to testing for statistical significance, known as equivalence testing, is little used in educational research. Equivalence testing is useful in situations where the researcher wishes to show that two means are not statistically different. A common equivalence test for comparing the means of two independent samples is reviewed. A simulation study assessed the relationships among effect size, sample size, statistical significance, and statistical equivalence. An example of typical educational research data is reanalyzed using equivalence methodology. A tentative conclusion is drawn about the magnitude of effect size needed to be important.
