Dear All,

I am trying to build a review of the sampling methodology currently used
to conduct market research and opinion polls through the internet. I am
basically trying to find out:

a) which probability samples/panels are available online and how are
their built?
b) what strategies are used by companies using convenience samples to
generalize their survey results to the (online/general) population?
c) Are you aware of incorrect claims about generalizing online survey
results to larger populations?

Thank you in advance for your comments.

Luca
