A VBA-based Simulation for Teaching Simple Linear Regression
p. 36 Gregory Todd Jones, Reider Hagfvedt & Kari Jones
In spite of the name, simple linear regression presents a number of conceptual
difficulties. particularly for introductory students. This article describes
a simulation tool that provides a hands-on method for illuminating the relationship
between parameters and sample statistics.
Classical versus Bayesian Inference: A classroom illustration p.
42 Thomas Woolley
Estimating the proportion of brown M&M's by classical methods and by a
simple use of Bayes' theorem for finite outcomes illustrates the differences
in method and the practical consequences.

Charts in Excel - A Series Matter p. 49 Neville
Hunt & Houshang Mashoudy
The Chart Wizard in Microsoft Excel is supposed to make chart drawing so easy
that a child can do it, yet many intelligent adults fail to use it successfully.
This article suggests some simple principles that resolve many of the difficulties.
CLASSROOM NOTES
An Upper Bound on the Value of the Standard Deviation p.54
John S Croucher
This article derives a simple upper bound for the sample standard deviation
that could be useful in guarding against gross errors of calculation.
Of Poohsticks and p- values: Hypothesis Testing in the Hundred
Acre Wood p. 56 Eric D Nordmoe
A walk through Milne's Enchanted Forest leads to an unexpected encounter
with hypothesis testing.
A Useful Example when Teaching Hypothesis Testing p. 59 Frederick
Wiseman
This article describes an example which is useful when teaching hypothesis
testing in order to highlight the interrelationships that exist among the
level of significance, the sample size and the statistical power of a test.
The example also allows students to see how what they lear in the classroom
directly affects the content of some of the commercials that they watch on
television.
