Last month in “The Analysis of Experimental Data,” I presented a method for analyzing experimental data that was built on the use of the range statistic as a measure of dispersion.

Since these questions can be a barrier to the effective analysis of data, they deserve to be answered.

History

Dr. Wheeler, I have always been fascinated by the history of statistics - where things came from. "The Lady tasting Tea", of course, comes to mind. Thanks for the historical perspective you provided in this and many other of your writings.
