Dear Steve Weir, Thank you for posting your survey on the web and requesting volunteers to fill it out. After you have collected the results, please throw them away.
Now that I've got your attention... :-) I'm serious; your results will be invalid, and they should be thrown away. Here's the problem: When you take a survey, you are making assumptions about a given population based on a sample. That's what statistics is. Any statistician will tell you that for a sample to be valid, it must be a random sample across the population. A VOLUNTEER SURVEY IS NOT RANDOM. The survey takers self-select, based on some criteria. It doesn't matter why they decide to take the survey; no matter the reason, they are not a random sample. The reason I'm making a big deal out of this is that I've seen several such survey requests, usually for a senior project or master's thesis. We're getting people writing up conclusions based on faulty surveying techniques -- the conclusions could well be wrong. So, please provide me the name of your advisor, and I will write him and explain why your master's thesis should be rejected. :-) Seriously, you need to withdraw this survey request, and design your sample to be representative of the population. You may want to trek over to your local statistics department; I'm sure they will be happy to help you.
