I present an active learning classroom exercise illustrating essential principles of one-way
analysis of variance (ANOVA) methods. The exercise is easily conducted by the instructor and
is instructive (as well as enjoyable) for the students. This is conducive for demonstrating many
theoretical and practical issues related to ANOVA and lends itself to multiple possible
configurations of ANOVA results, leading to rich classroom discussion and deeper student
understanding of real-world applications of the methods.
