Show Me the Magnitude! The Consequences of Overemphasis on Null Hypothesis Significance Testing.
Lane, Ginny G.
For years, researchers have debated the misinterpretation of the null hypothesis significance test (NHST). Many researchers overemphasize the results of the NHST and underemphasize or even omit effect size measures. This paper addresses the common mistaken perceptions regarding the NHST. Several common effect size estimates are discussed. A small data set is utilized to demonstrate how reliance on statistical significance without consulting effect size estimates can lead to erroneous conclusions. How interpretation of measures of effect size can provide the researcher with better information about the nature of results is discussed. (Contains 2 tables and 17 references.) (Author/SLD)
