I'm currently working in a new interactive museum in Mexico City, we just
started the process of evaluate some exhibits in the design and production
phase (formative). I'm having problems to explain why this kind of
evaluation does not need large statistical samples, great part of the team
thinks that we need to have representatives samples and, I read in some
classical texts (Screven, Griggs, Hein) that this is not necessary nor
practical.

Does any one have a good methodological frame to pick good samples for this
kind of evaluation? Or does any one could recommend me the "Formative
evaluation handbook"? I prefer things I can consult through web because in
Mexico is difficult to get those books, although we can buy some basic and
interesting texts.

Thanks in advance
