All introductory statistics students must master certain basic descriptive statistics, including means, standard deviations and correlations. Students must also gain insight into such complex concepts as the central limit theorem and standard error. This article introduces and describes the Friendly Introductory Statistics Help (FISH) computer program, which is free and easy-to-use software designed to help students learn such introductory statistical concepts.
Cooking and tasting chicken soup in three different pots of very different size serves to demonstrate that it is the absolute sample size that matters the most in determining the accuracy of the findings of the poll, not the relative sample size, i.e. the size of the sample in relation to its population.
In this article, we present the main findings of an experiment which involves teaching statistics in the 5th and 6th grade classes of Greek elementary schools. This experiment focused on the evaluation of the potentials of teaching statistical concepts and methods using directed projects.
This article describes a simple classroom activity that helps students immediately visualize and understand the meaning and mathematical properties of the Poisson distribution.
In this article, we study the Monty Hall three doors problem. A fully general solution and several new approaches are presented, including a Bayesian analysis.
This article gives a method of finding discrete approximations to continuous probability density functions and shows examples of its use, allowing students without calculus access to the calculation of means and variances.
This article discusses some strategies for playing roulette, making use of the binomial distribution and Normal approximation.
This article describes an activity through which students collect data and explore ways to display them through graphs and charts. It also motivates various summary measures for location, spread and shape. Finally, it gives an introduction to concepts of validity, reliability and unbiasedness.
A lottery coincidence provides the background for discussing the assessment of probabilities and the definition of events.
This article describes how Chernoff faces can be drawn in Microsoft Excel.
