This article develops nineteen distributions from a simple coin-tossing experiment.
This article evaluates and explores the correlation (+0.892) between the United States federal election winner and the most recent Washington Redskin home-game winner, a relation perfectly linked for 17 of 18 elections since franchise inception in 1936.
This article illustrates that not all statistical software packages are correctly calculating a p-value for the classical F test comparison of two independent Normal variances. This is illustrated with a simple example, and the reasons why are discussed. Eight different software packages are considered.
Reasoning with data is already pervasive in society, and its importance as a life skill is increasing. We argue that the current statistics curriculum in the United Kingdom at the secondary level does not prepare our young people adequately, and suggest ways in which it could be improved.
The statistical thinking exhibited by 14-19 year-old students during clinical interview sessions is described. The students' thinking with regard to fundamental statistics concepts is reported in order to help inform instructional practice.

For the casino game Keno we determine optimal playing strategies. To decide such optimal strategies, both exact (hypergeometric) and approximate probability calculations are used. The approximate calculations are obtained via the Central Limit Theorem and simulation, and an important lesson about the application of the Central Limit Theorem is reinforced.
This article shows how consideration of seating arrangements in theatres can be used as a basis for constructing an interesting probability model.
This article considers some probability calculations for a television game show.
