User:Taxman/Article quality review

Source: Wikipedia, the free encyclopedia.

A number of surveys of article quality have been done by Wikipedia editors. All I've seen so far attempted to get an idea of the percentage of quality articles among a set of randomly chosen articles. The problem with this is that it includes new articles which are on average shorter and of poorer quality. What I didn't see was an attempt to measure average article quality improvement for existing articles. I plan to focus on articles that have existed for 2 years or more to see if I can confirm the assumption that articles improve substantially over time.

As of July 30, 2006, there are about 1.28 million articles, while the 300,000 article threshhold was reach on July 7, 2004. Therefore a quarter is an upper bound for the number of articles have existed for 2 years, but factoring in deletions the number should be at least somewhat less than that. The following are the first 100 results from the random article function.
