abstract = {Summary: We demonstrate how the DEWIS e-Assessment system may use embedded R code to facilitate the assessment of students' ability to perform involved statistical analyses. The R code has been written to emulate SPSS output and thus the statistical results for each bespoke data set can be generated efficiently and accurately using standard R routines. This enables students' answers, generated from their application of SPSS, to be marked and appropriate feedback supplied back to them automatically. Staging is used between different parts of the e-Assessment to replicate the natural stages of a complete statistical analysis. This allows students the freedom to work away from the e-Assessment; they may view the relevant stage an unlimited number of times prior to submitting their answers for that stage. The technical challenges of setting up the e-Assessment in this way are discussed as well as the rationale for adopting this pioneering approach.},
