So, how many users are needed to make it > representative? Well you would want to poll a group that you knew had been active for a while, and had some certainty that they were unique individuals. I know several people who register 3-4 accounts on forums so that they can vote more often or play games. I don't know how many people do that but the risk usually makes these sorts of polls have lower confidence levels to around 50%. [EG a statician looking at the data would say that it is no more valid than flipping a coin.] This is NOT to say that the poll end data is in the end wrong just that trying to be more confident in the data (whether it was that Fast, Slow, or Cowboy Bob) can not be determined. So if the data had shown that people wanted conservative, I would hopefully be saying the same things if people said it proved their point. A more valid poll might be possible by the following method: If we assumed that the people who had been registered in FAS for over 6 months and had signed the CLA met the first two definitions, you would need to randomly select about 3000 of them and have at least 600 answer the poll to have (i think) a 90% confidence level in the poll. I think the questions need to be simple yes/no ones to qualify for the 'easiest' tests, multiple choice results require something like multiple asking worded slightly different or some such thing. Again this is from a class I took 20 years ago so a real mathematician, psychologist, etc would know better. I also do not want to imply or say that this is wanted/possible etc. There would be a whole range of issues that would have to get approval or checked to see if assumptions were valid. -- Stephen J Smoogen.
