Summary: We demonstrate how the DEWIS eAssessment 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 eAssessment to replicate the natural stages of a complete statistical analysis. This allows students the freedom to work away from the eAssessment; 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 eAssessment in this way are discussed as well as the rationale for adopting this pioneering approach.
