I'm working on a statistics class for my Business Administration degree, so I decided to collect data regarding people's DVD collections. If you could take the time to answer this poll, I would greatly appreciate it.
My sole college statistic class, granted it was only a 200 level course, was generally obsessed with plotting data so as to determine standard deviations along a bell curve. It's interesting to me that you're looking for fairly precise data on one end of the spectrum with divisions based on quantities of 50-75 titles, but you're not on the other end with everyone with over 400 titles in one category (40% of respondents thus far). So how will this data be useful to you?
Not to mention I don't think you'll find a fair representation of society about DVD ownership at a place called DVDtalk (unless you are specifically looking for stats on DVD fans in which case I agree w/ Yakuza in that you need more categories). Anyway FWIW I started collected in '99 and have close to 900 titles now.

I know it's for academia and everything, but we've already got danwiz's thread linked above. I would also suggest this thread, which has plenty of data for you, but is a year old... maybe that won't matter. However, it does go into more specific details for the higher end of the number spectrum (> 400-500 discs).
