The reason government studies use the probability sampling methods is that they give a picture generalizable to the population, even despite the falling response rates (people-press.org/2012/05/15/…). Online panels may produce errors of about 10% on some items, no matter whether they have 1000 participants or 20000 participants -- there were plenty of talks about online panels at the recent AAPOR conference showing this. | |
