Application of the numerical method to the art of Medicine was regarded not as a “trivial ingenuity” but “an important stage in its development”; thus proclaimed Professor Bradford Hill, accepted as the father of medical statistics, a study still largely unintelligible to the mass of medical practitioners. The need for Statistics is the elucidation of the effects of multiple causes; this represents the essence of the statistical method and is most commendable. Conclusions reached empirically under statistical scrutiny have mistakes and fallacies exposed. Numerical methods of analysis, the mathematical approach, reveals data relating to factors in an investigation, which might be missed in empirical observation, and by means of a figure states their significance in the whole. A simplified example is the numerical analysis of food poisoning, which alone determines the commonest causative organisms, the commonest food vehicles and the organisms which affect different foods, as well as changes in the pattern, e.g., the rising incidence of S. agona and the increase of turkey (and the occasions on which it is served, such as Christmas parties), as a food poisoning vehicle. The information data enables preventive measures to be taken. The ever‐widening fields of Medicine literally teem with such situations, where complexities are unravelled and the true significance of the many factors are established. Almost every sphere of human activity can be similarly measured. Apart from errors of sampling, problems seem fewer and controversy less with technical methods of analysis then on the presentation and interpretation of figures, or as Bradford Hill states “on the application of common sense and on elementary rules of logic”.
