People who do x are more likely to y

I'd like to read about unexpected statistical correlations that begin to emerge when companies or academics use data mining to analyze behaviour in large groups of people. I'm looking for articles/sites that are a little more serious than this (found while searching Metafilter for this topic). More like this (NYT: Target is able to predict that some customers are pregnant before their children are born). Thanks for your recommendations! [more inside]

Calculating a binomial distribution confidence interval for a particular experiment

[StatisticsFilter] I’m trying to understand the extent that the statics of a particular experiment can be evaluated and trying to relate that to a 95% confidence interval. The experiment is considered “a standard”, but I want to keep the discussion as “high level” as I can so that we focus on only the relevant details.

Creating my own crime map

I want to create a "crime map" of a city over time. I know the dates of the crimes, and I know the physical address. I'd like for the crime map to be something that I could show a crowd in a presentation such that the audience members could witness for themselves how a particular part of the city changed as time went on. I was thinking of Gapminder as the ideal, but spatially and dynamic instead of simply numbers. I suppose it'd be possible to get something up and going with GIS, but I was wanting to do it in a way that was idiot-proof as this is only valuable to me if I can do it easily without a ton of time learning some new program.
