Britta I was involved in a project looking at affective effects of fieldwork in which we used pre and post questionnaires. We maintained anonymity but kept the potential for pairing by having the students use nicknames. We used t-tests for statistical analysis. Alison Stokes did a similar thing in a later fieldwork project.

I am about to write things up for a scientific paper and I am not sure whether I should use repeated measurements or two series of t-tests to analyze the quantitative questions. Does anyone have experience with this topic? There are just too many papers out there and I am not sure about their reliability. I would very much appreciate any suggestions. Thank you very much Britta
