This dataset is designed to teach basic approaches for including age as a non-linear predictor in regression analysis using polynomial regression. The dataset example expands upon another dataset example which looks at age as a continuous or categorical variable when analysing survey data. The dataset is a subset of data derived from the Wellcome Trust Monitor Survey 2009, and the example examines ways of exploring the relationship between age and a measure of science knowledge. The dataset file is accompanied by a Teaching Guide, a Student Guide, and a How-to Guide for Stata.
