“…First, statistical graphics became popularized and entered the main stream. A spate of English textbooks began to appear, for example, Bowley (1901), Peddle (1910), Haskell (1919), Karsten (1925), college courses on graphics were developed (Costelloe, 1915;Warne, 1916), and statistical charts, perhaps mundane, entered standard use in government (Ayres, 1919) and commerce. 23 Of course, Galton, Pearson and even Fisher were enthusiastic graph people, but many of those who extended their ideas (e.g., F. Y. Edgeworth, G. U. Yule and even Pearson himself) turned their attention to mathematical and analytic aspects of correlation, regression and general theories of statistical distributions.…”
