== History ==
Many EDA ideas can be traced back to earlier authors, for example:
* [[Francis Galton]] emphasized [[order statistic]]s and [[quantile]]s.
* [[Arthur Lyon Bowley]] used precursors of the stemplot and [[five-number summary]] (Bowley actually used a "[[seven-number summary|seven-figure summary]]", including the extremes, [[decile]]s and [[quartile]]s, along with the median&mdash;see his ''Elementary Manual of Statistics'' (3rd edn., 1920), p.&nbsp;62<ref>Elementary Manual of Statistics (3rd edn., 1920)https://archive.org/details/cu31924013702968/page/n5</ref>– he defines "the maximum and minimum, median, quartiles and two deciles" as the "seven positions").
* [[Andrew S. C. Ehrenberg|Andrew Ehrenberg]] articulated a philosophy of [[data reduction]] (see his book of the same name).

The [[Open University]] course ''Statistics in Society'' (MDST 242), took the above ideas and merged them with [[Gottfried Noether]]'s work, which introduced [[statistical inference]] via coin-tossing and the [[median test]].
