statistics

A discipline, principally within applied mathematics, concerned with the systematic study of the collection, presentation, analysis, and interpretation of data.

Statistics is the only mathematical field required for many social sciences.

As for statistics, the foundations include, on any interpretation of which I have ever heard, the foundations of probability, as controversial a subject as one could name. As in other sciences, controversies over the foundations of statistics reflect themselves to some extent in everyday practice, nut not nearly so catastrophically as one might imagine.[…]It is hard to judge, however, to what extent the relative calm of modern statistics is due to its domination by a vigorous school relatively well agreed within itself about the foundations.
