In Praise of the Null Hypothesis Statistical Test

Edit this page


Jacob Cohen (see record 1995-12080-001) raised a number of questions about the logic and information value of the null hypothesis statistical test (NHST). Specifically, he suggested that: (1) The NHST does not tell us what we want to know; (2) the null hypothesis is always false; and (3) the NHST lacks logical integrity. It is the author’s view that although there may be good reasons to give up the NHST, these particular points made by Cohen are not among those reasons. When addressing these points, the author also attempts to demonstrate the elegance and usefulness of the NHST.
