Another post on dating strategies
Megan of From the archives won’t be surprised that this NYT article, claiming that:
One survey, recently reported by the federal government, concluded that men had a median of seven female sex partners. Women had a median of four male sex partners. Another study, by British researchers, stated that men had 12.7 heterosexual partners in their lifetimes and women had 6.5. But there is just one problem, mathematicians say. It is logically impossible for heterosexual men to have more partners on average than heterosexual women. Those survey results cannot be correct.
is already getting play in the blogosphere. The only thing is that it isn’t logically impossible, at least as the author presents it. Ask Andrew Gelman
Jeff’s response: MEDIANS??!! Indeed, there’s no reason the two distributions should have the same median. I gotta say, it’s disappointing that the reporter talked to mathematicians rather than statisticians. (Next time, I’d recommend asking David Dunson for a quote on this sort of thing.) I’m also surprised that they considered that respondents might be lying but not that they might be using different definitions of sex partner. Finally, it’s amusing that the Brits report more sex partners than Americans, contrary to stereotypes.
