This resource requires students to calculate a test statistic from the following three tests; chi-square, Spearman rank correlation and standard error and 95% confidence limits. Designed to give students the opportunity to select the appropriate statistical test to apply to a certain set of data. Students collect data by observing film footage of the ants’ behaviour then analyse the data using the chi-square test and interpret the outcome in relation to their test statistic. There are notes with information on leaf-cutting ants and suggested answers for all tasks. Written by Richard Bottrill.

Brilliant resource
Fantastic - just what I needed to get my A2 students engaged with statistics
