  1. Child’s Play - Reasoning with Multidimensional Data Jim Ridgway, James Nicholson and Sean McCusker jim.ridgway@durham.ac.uk University of Durham www.dur.ac.uk/smart.centre/ OECD March 07 Jim Ridgway, James Nicholson and Sean McCusker

  2. Child’s Play – Reasoning with Multi-Dimensional Data • Play therapy • Alcohol, Fast Birds, and Sexually Transmitted Infections • Research • Testing smart 9 and 13 year olds – they can reason with multidimensional data • Generalising to representative students – they can do it too • What don’t we know • The threat of education • What are we doing about it all OECD March 07 Jim Ridgway, James Nicholson and Sean McCusker

  3. Child’s Play • Sexually Transmitted Infections • Alcohol • Fast Birds • http://www.ic.nhs.uk/pubs/alcoholeng2006/alcoholtables/file • www.hpa.org.uk/infections/topics_az/hiv_and_sti/epidemiology/datatables2005.htm In collaboration with CCEA, QCA and The Information Centre OECD March 07 Jim Ridgway, James Nicholson and Sean McCusker

  7. The Threat of Education • Condorcet le savoir liberateur and all that… • UK students are taught 1930s statistics (Ridgway et al, 06) • the 1930s principle was fine – ‘take something of interest and mathematise it’ OECD March 07 Jim Ridgway, James Nicholson and Sean McCusker

  8. Child’s Play – What don’t we know? What do/can people understand from multivariate data – in an emerging field? What can people learn as they interact with data? OECD March 07 Jim Ridgway, James Nicholson and Sean McCusker

  9. Some Heuristics for Playing • Critique the quality of the data • Describe and explore before you model and explain • Check that the effect size is a lot bigger than the likely measurement error • Look for interactions, and think about ‘data surfaces’ • Think about possible confounding variables • Disaggregate data – are the patterns the same? • Be cautious about ‘causality’ – especially in observational data OECD March 07 Jim Ridgway, James Nicholson and Sean McCusker

  10. Our Current Work • Interface design • Generic shells as freeware • Empirical studies on difficulty • Curriculum development • Modelling disease spread • Risk taking by young people • Drugs, sex, obesity, alcohol abuse • Conceptual analyses • What is worth knowing? • What develops? • How? • Collaborating! - http://www.dur.ac.uk/smart.centre OECD March 07 Jim Ridgway, James Nicholson and Sean McCusker
