Title: Reasoning with Multivariate Evidence

Authors: Jim Ridgway, James Nicholson and Sean McCusker, United Kingdom

Abstract: We report a study where 195 students aged 12 to 15 years were presented with computer-based tasks that require reasoning with multivariate data, together with paper-based tasks from a well established scale of statistical literacy. The computer tasks were cognitively more complex, but were only slightly more difficult than paper tasks. All the tasks fitted well onto a single Rasch scale. Implications for the curriculum, and public presentations of data are discussed.

Keywords: Multivariate Data, Curriculum, Rasch Scaling, Hierarchies, Statistical Reasoning, Statistical Literacy, Assessment.
