Zeal for statistics sometimes blinds one to its limitations as an instrument of discovery, as a form of language, as a contributor to understanding, as a device for holding factors constant, and as an aid in constructing a composite account; as well as its obvious limitations in fields where the social sciences deal with the unique. As W.I. Conceivably everything dealing with the collection, processing, analysis and interpretation of numerical data belongs to the domain of statistics.
