Kiss High Blood Pressure Goodbye: The Relationship between Dark Chocolate and Hypertension P34. Eric D. Nordmoe
This article reports on a delicious finding from a recent study claiming a causal link between dark chocolate consumption and blood pressure reductions. In the article, I provide ideas for using this study to whet student appetites for a discussion of statistical ideas, including experimental design, measurement error and inference methods.
Inspired by Statistics? P39. Tracey Carr
This article considers being inspired by statistics as both a learner and a teacher. It looks particularly at a task involving research of Minard’s Map, a statistical representation, to create and present a statistical task for a learner. It describes how the use of imagery, and the enthusiasm that developed as the map and its context were explored by the teacher, were passed on to the learner.
Pricing Models Using Real Data P44. Tom Obremski
A practical hands-on classroom exercise is described and illustrated using the price of an item as dependent variable throughout. The exercise is well-tested and affords the instructor a variety of approaches and levels.
Another Approach to Generalizing the Mean P49. J. Matejaš and V. Bahovec
This article presents a new approach to generalizing the definition of means. By this approach we easily obtain generalized means which are quite different from standard arithmetic, geometric and harmonic means.
Teaching Confidence Intervals Using Simulation P53. Reidar Hagtvedt, Gregory Todd Jones and Kari Jones
Confidence intervals are difficult to teach, in part because most students appear to believe they understand how to interpret them intuitively. They rarely do. To help them abandon their misconception and achieve understanding, we have developed a simulation tool that encourages experimentation with multiple confidence intervals derived from the same population.
Paper-Clip Case: A Practical Activity to Improve Statistical Thinking for Engineering Students P57. E. Viles
In this article I present an activity introducing statistical concepts to engineering students to help them develop inductive reasoning and problem-solving skills.
