Interesting statistical comment. Obviously with independent and large samples assumed to come from the same distribution, the mean heights would be the same in Chicago and New York. But that begs the question. Why would their mean heights be exactly 5'10"? ie, sure, the crowds in various places converge on the same pitch...but why on such specific pitches? Presumably, a social phenom, in which some subset of folks in the crowd concentrate their energies on the "traditional" chant pitches, and the rest of the pitch-unsure-to-pitch-deaf simply go along with them?
