I wanted to conduct some statistical analysis on certain dimensions relevant to the development of the site and was wondering how to access data in order to construct a data set for that. For example, how would I get data to calculate the correlation between # of edits of questions and their upvotes?

I checked out https://meta.askubuntu.com/questions/11641/where-to-access-some-statitics and https://meta.askubuntu.com/questions/13618/direct-access-to-askubuntu-reputation-statistics which don't provide sufficient information.
