The word statistik comes from the Italian word statista. It means a statesman. Dr. E.A.W. Zimmerman introduced the work statistics into England and its use was popularized by Sir John Sinclair through his work, Statistical Account of Scotland 1791-1799.

Decision theory


This branch of statistics deals with decisions under risk and uncertainty
