The Minimally Important Difference Significant Criterion for Sample Size.

Harris, Richard J.; Quade, Dana

Journal of Educational Statistics, v17 n1 p27-49 Spr 1992

A method is proposed for calculating the sample size needed to achieve acceptable statistical power with a given test. The minimally important difference significant (MIDS) criterion for sample size is explained and supported with recommendations for determining sample size. The MIDS criterion is computationally simple and easy to explain. (SLD)
