@Sue. At the risk of repeating myself, I'd say the poll is a prediction based on a survey and the theory is the mathematical statistics underlying the technique(s) used. In a well designed survey some lying or inconsistencies can be identified, so coupled with analysing sample attributes it should be possible to estimate an error margin. Changing minds is something that happens, polls should be more accurate closer to the event. But polls are just predictions so are not going to be completely accurate. I did some statistics as part of my maths degree but never really liked it: lies, damned lies, etc ... except quantum mechanics which obviously works as we have lasers, etc. Just wish Schrödinger had put a politician in his box ... |
