Visualizing Statistical Concepts
Hi-Res PDFAbstract
Because statistical concepts such as least-squares fitting are often experienced as abstract, their visualization can be a helpful didactic tool, provided that this is done correctly. Unfortunately, the example in Figure 1 on page 1884 of the December 2006 issue of JCE fails the latter test.

Stephen L. R. EllisonJournal of Chemical Education2009 86 (7), 809Including (0,0) as Experimental Data
Stephen L. R. EllisonJournal of Chemical Education2009 86 (7), 809The argument that a zeroed instrument is expected to provide a point at (0,0) is specious and misleading. An actual observation at zero concentration on a zeroed instrument is practically never zero except by chance or censoring.
