Better Articulating Normal Curve Theory for Introductory Mathematical Statistics Students

摘要

In the August issue of TAS, Griffith's (2013) article and its catchy title drew my immediate attention. At first, I felt sympathy with the message that this author was trying to get across through his opening statements found in the abstract, and I quote: "This article addresses a gap in many, if not all, introductory mathematical statistics textbooks, namely transforming a random variable so that it better mimics a normal distribution. Virtually all such textbooks treat the subject of variable transformations, which furnishes a nice opportunity to introduce and study this transformation-to-normality topic ..."
