Better statistics for better decisions: Rejecting null hypotheses statistical tests in favor of replication statistics
Federico Sanabria, Peter R. Killeen · Psychology in the Schools · 2007
Despite being under challenge for the past 50 years, null hypothesis significance testing (NHST) remains dominant in the scientific field for want of viable alternatives. NHST, along with its significance level p, is inadequate for most of the uses to which it is put, a flaw that is of particular interest to educational practitioners who too often must use it to sanctify their research. In this article, we review the failure of NHST and propose p(rep), the probability of replicating an effect, as a more useful statistic for evaluating research and aiding practical decision making.
