One- versus Two-Tailed Hypothesis Tests in Contemporary Educational Research.
Pillemer, David B.
Educational Researcher, v20 n9 p13-17 Dec 1991
Adherence to the arbitrary 0.05 level of significance as a benchmark for decisions about publishing research largely accounts for the popularity of one-tailed hypothesis tests. Effect size estimates, accompanied by confidence intervals or exact two-tailed probabilities, are generally more compatible with the growing meta-analytic view of social science. (SLD)
