History
Many EDA ideas can be traced back to earlier authors, for example:
- Francis Galton emphasized order statistics and quantiles.
- Arthur Lyon Bowley used precursors of the stemplot and five-number summary (Bowley actually used a "seven-figure summary", including the extremes, deciles and quartiles, along with the median - see his Elementary Manual of Statistics (3rd edn., 1920), p. 62 – he defines "the maximum and minimum, median, quartiles and two deciles" as the "seven positions").
- 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.
