Noisy information can be useful. I've taken courses in statistics so I think I understand the problems with surveys. There can be a lot of sampling noise (like with opinion polls) and there can be survey bias in the way the sample is constructed. I realize that a difference of a couple of notches is just sampling noise. What I want to find out is whether there are any brands that are *really bad*.
Statistics works with known facts (correct me if iam wrong).
If you don't know what brands are buplicates of others, and who is slinging bull (overexagerating: it happens among the pros here and else where) and what statements by HOs are making based more on suggestion then actual fact, how will you be able to extract any honest and unbiased and subjective conclusions?
