Relative risk analysis of educational data
Abstract: This paper demonstrates the use of relative risk, a statistic which is widely used in other areas but currently underutilised in education. Relative risk analysis provides a language for comparing educational outcomes as well as statistical tests of significance. We illustrate this statistic with data on students' understanding of decimal notation. In particular, we determine differences in how misconceptions operate at different ages, by analysing the relative risk of primary and secondary students persisting with particular misconceptions, and becoming experts.
