The American Statistician, 2013, vol. 67, issue 3, 129-133

Abstract: This article reexamines the famous barley data that are often used to demonstrate dot plots. Additional sources of supplemental data provide context for interpretation of the original data. Graphical and mixed-model analyses shed new light on the variability in the data and challenge previously held beliefs about the accuracy of the data. Supplementary materials for this article are available online.
