      the box plot is often assumed not to need explanation beyond such texts. Box plots had several under-appreciated precursors under different names, including range bars (Spear 1952, 1969) and dispersion diagrams in geography and climatology (e.g., Crowe [1933]andMonkhouse and Wilkinson[1971]). Despite this earlier history, my guess is that box ...
