Statistics

One of his most famous contributions to statistics is sequential sampling. Friedman did statistical work at the Division of War Research at Columbia, where he and his colleagues came up with the technique. It became, in the words of The New Palgrave Dictionary of Economics, "the standard analysis of quality control inspection". The dictionary adds, "Like many of Friedman's contributions, in retrospect it seems remarkably simple and obvious to apply basic economic ideas to quality control; that, however, is a measure of his genius."
