The Language of Statistics p. 34 Margaret Rangecroft
The discussion of problems associated with the use of language, specifically vocabulary and symbolism, is extended from the teaching and learning of mathematics to particular areas of statistics.
The Binomial and Hypergeometric Probability Distributions in Jury Selection p. 38 Jude T Sommerfield
This article considers the composition of juries, asking whether this is representative of the general population from which juries were drawn. The binomial and hypergeometric distributions are used for probability calculations. Several example applications of both of these distributions are given, addressing racial, sex and age distributions in various cases.
More Happy Returns to the Birthday Problem p. 43 Michael Bedwell
This article shows how the birthday problem can be used to introduce the exponential distribution.
Using Consulting for Teaching Elementary Statistics p. 46 John Truran and Anne Arnold
Consulting in Statistics is usually deferred until at least near the end of a first degree, but this article shows how some aspects can be effectively taught to students in upper secondary or early tertiary courses in a way which reinforces their learning of standard basic concepts. We suggest that the existence of a real client adds a degree of realism not available in other ways, and emphasizes to students the importance of blending statistical calculations with meaningful communication.
Spreadsheets as a Simulation Tool for Solving Probability Problems p. 51 M I Ageel
This article illustrates the use of spreadsheets as a simulation tool for solving a collection of probability problems.
Classroom and Worksheet Activities across the Curriculum p. 55 Doreen Connor and Peter Holmes
This article shows how teachers can create useful classroom activities to underpin data-handling methods for pupils aged 7 – 19. We use the data base of responses from the UK CensusAtSchool project that are available for pupils and teachers.
An International Resource for Learning and Teaching p. 59 Doreen Connor and Neville Davies
This article compares the national curriculum data-handling specifications of the UK, South Africa, Australia and New Zealand and shows how data from the CensusAtSchool project can be used to enhance the data handling capabilities of pupils in these countries. These data can also provide enhanced opportunities for the integration of ICT into core curriculum activities. Some ideas to enable teachers of statistics to create classroom teaching material with an international flavour are also provided.
Web-based Project and Key Skills Work p. 62 Doreen Connor, Neville Davies and Bradley Payne
Pupils in England and Wales are increasingly being asked to undertake investigative-type work, be it the new compulsory projects in data-handling for GCSE Mathematics (age 14-16) (see Browne, 2002) or the Key Skills topic application of number. This article shows how teachers can generate realistic project scenarios using real data and produce indicative model solutions from the same data. The projects range from simple presentational problems for data, through hypothesis testing to complex modelling scenarios.
Understanding Correlation p. 66 A V Kharshikar and S Kunte
This article uses a simple counter-intuitive example to point out a common misinterpretation of correlation. l
Statistical Laboratories Using Minitab, SPSS and Excel: A Practical Comparison p. 68 Tania Prvan, Anna Reid and Peter Petocz
This article discusses three statistical laboratories – on descriptive statistics, statistical inference and regression – for introductory statistics courses. They are presented in Minitab, SPSS and Excel, three packages widely used in statistical education, and are available on the Web.
LETTER TO THE EDITOR p. 75 Ruma Falk and Ester Samuel-Cahn
Another reference to Lewis Carrol’s pillow problem that was the substance of a recent article in Teaching Statistics by the writers.
