Origin

 

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.

 

We can identify three subdivisions in statistics now.

Large amount of data is compressed into tables and charts in this branch of statistics.

This branch of statistics deals with decisions under risk and uncertainty
