The areas described on the previous page are broken down into a number of modules that cover major subjects such as demography and questionnaire design.

The modules are broken into topics and most topics have a series of interactive exercises. For many of the topics there are "expert commentaries" provided by the authors of the exercises.

There is also a glossary which relies and expands on relevant entries in the IEA sponsored A Dictionary of Epidemiology (Last, Oxford University Press)
