The idea that statistical significance should be abandoned has received a lot of attention recently but it is not new, and efforts to replace p-value has been underway for some time. Perhaps the largest effort involves the development of effect size statistics. However, the large number of alternative effect size measures that have been proposed (Huberty, 2002) indicates that there are unresolved problems in this field as well. Only a small part of the large literature on these problems is cited here.
