Making statistical methods in management research more useful: some suggestions from a case study

Abstract

I present a critique of the methods used in a typical paper. This leads to three broad conclusions about the conventional use of statistical methods. First, results are often reported in an unnecessarily obscure manner. Second, the null hypothesis testing paradigm is deeply flawed: estimating the size of effects and citing confidence intervals or levels is usually better. Third, there are several issues, independent of the particular statistical concepts employed, which limit the value of any statistical approach: e.g. difficulties of generalizing to different contexts, and the weakness of some research in terms of the size of the effects found. The first two of these are easily remedied: I illustrate some of the possibilities by re-analyzing the data from the case study article. The third means that in some contexts a statistical approach may not be worthwhile. My case study is a management paper, but similar problems arise in other social sciences.
