Interpreting Statistical Significance Test Results: A Proposed New "What If" Method.
Kieffer, Kevin M.; Thompson, Bruce
As the 1994 publication manual of the American Psychological Association emphasized, "p" values are affected by sample size. As a result, it can be helpful to interpret the results of statistical significant tests in a sample size context by conducting so-called "what if" analyses. However, these methods can be inaccurate unless "corrected" effect sizes are used. This paper proposes a new method by which "what if" analyses can be conducted using estimated true population effects. Two appendixes contain EXCEL spreadsheet commands for previous "what if" methods and the present method. (Contains 4 tables and 48 references.) (Author/SLD)
