Where can I find real data to do statistic tests on?

I have a statistics project and need to find data to run statistic tests on (ex:Confidence Intervals, Significance Tests). I must find real data to test. Suggestions or links to data would be appreciated.

On the Web, try PubMed. It's a place where medical research is published. You can get abstracts for free. These research papers are full of things like "200 patients were studied, of whom 179 completed the six month study. 85 patients showed marked improvement in the active group while in the control group, only 6% showed marked improvement."
