The datasets, often in .txt (text), .dat (data) or .csv (comma separated variable files) form have been chosen to suit the development or assessment of the statistical relationships described in the Mathematics units. Excel files that could be used by students or for demonstration. These articles could be provided to students to stimulate interest in statistics or to demonstrate questionable use of statistics. They are from the database provided by the Mercury newspaper in Hobart, but the issues addressed are of national relevance. These articles are included as a resource for teachers. They report approaches to statistics teaching, classroom use of data sets and historical background. Questions are included that could be used for assessment or in teaching.
