  1. Toward evidence-based medical statistics. 1 : The P value fallacy.

    Article - En anglais

    An important problem exists in the interpretation of modern medical research data : Biological understanding and previous research play little formal role in the interpretation of quantitative results.

    This phenomenon is manifest in the discussion sections of research articles and ultimately can affect the reliability of conclusions.

    The standard statistical approach has created this situation by promoting the illusion that conclusions can be produced with certain « error rates, » without consideration of information from outside the experiment.

    This statistical approach, the key components of which are P values and hypothesis tests, is widely perceived as a mathematically coherent approach to inference.

    There is little appreciation in the medical community that the methodology is an amalgam of incompatible elements, whose utility for scientific inference has been the subject of intense debate among statisticians for almost 70 years.

    This article introduces some of the key elements of that debate and traces the appeal and adverse impact of this methodology to the Pvalue fallacy, the mistaken idea that a single number can capture both the long-run outcomes of an experiment and the evidential meaning of a single result.
