How Shoddy Statistics Found A Home In Sports Research | FiveThirtyEight
Hopkins’s workaround for all of this, MBI, has no sound theoretical basis. It is an amalgam of two statistical approaches — frequentist and Bayesian — and relies on opaque formulas embedded in Excel spreadsheets1 into which researchers can input their data. The spreadsheets then calculate whether an observed effect is likely to be beneficial, trivial or harmful and use statistical calculations such as confidence intervals and effect sizes to produce probabilistic statements about a set of results.
