You assume that I meant showing the charts and graphs TO the girls.
Perhaps I meant using statistics to inform one's decisions about dating!
This is a very amusing statistics blog from the dating website OKCupid where they run analyses of their ridiculously huge body of data from users to sometimes answer silly questions but also sometimes provide really useful information about what statistically makes good first impressions, what questions you can ask to covertly learn highly correlated information about somebody without them realizing it (For instance, if somebody says that they do like the taste of beer, they are something like 2-3x more likely than the average member of the population to be willing to have sex on a first date, haha. Also less douchey things though, like how to ask about their political orientation without actually asking political things.):
Check it out, good stuff:
