Explaining the number of counterfactual cases needed to disturb a finding: a reply to Kuha and Sturgis

Publication Summary

Abstract This brief paper is an extension of our original paper What to do instead of significance testing? Calculating the ‘number of counterfactual cases needed to disturb a finding’, following a response by Jouni Kuha and Patrick Stugis. It shows how their response assists in the development of our idea of the ‘number needed to disturb’ (NNTD) a finding, and allows us to explain that idea further. NNTD allows researchers to summarise the scale, ‘effect’ size and attrition of a study in one figure.
