What constitutes a good survey? How many variables and choices would it need to have? Or, is a survey not a good form of finding ones opinion? For example, if I made a survey asking the public, "Who is the best actor?" Then, showed pictures to choose from, how am I supposed to know that they weren't picking the most attractive one? What would you consider a good survey and what would you consider a bad survey? I just need some opinions on this matter, thanks in advance.
