Testing for Statistical and Practical Significance: A Suggested Technique Using a Randomization Test.
Fraas, John W.; Newman, Isadore
This paper presents a testing procedure that incorporates three key elements. The first element is the use of non-nil null hypotheses. The second element is the determination of a practically significant level that is incorporated into the corresponding non-nil null hypothesis. The third element is the use of a randomization test to statistically test each non-nil null hypothesis. This procedure stresses two philosophical positions. First, the concepts of practical and statistical significance are both essential components in the evaluation process. Second, the use of this procedure encourages the researchers to consider the process of establishing the level of practical significance, not only as a statistical one, but also, as one in which the researchers would consider societal concerns and cost versus benefit comparisons. An appendix contains the computer program for the randomization test. (Contains 38 references.) (Author/SLD)
