Significance, effect sizes, stepwise methods, and other issues: Strong arguments move the field

The author asserts that editors should publicly declare their expectations and expose the rationales for editorial policies to public scrutiny. He arg ues that editorial policies ought to require effect size reporting, as thos e at 17 journals now do. He also argues (a) that score reliabilities should be reported; (b) that stepwise methods should not be used; (c) that struct ure coefficients should be interpreted; and (d) that if used wisely, confid ence intervals differ from hypothesis tests in important ways. The use of n oncentral t and F distributions to create confidence intervals about effect sizes also is appealing.
