This is something I've been meaning to experiment with for ages, but never got round to. I've just been reminded of it, because someone posted on a thread elsewhere with the assumption that "birthdays are randomly distributed" - which I've always assumed they're not. For a start, there's always a bit of a clump of birthdays round February/March, which I've always blamed on people having early summer holidays in June.

Now, I'm assuming that unlike, say, musical taste, incidence of birthdays among my friends list will at least be representative of the population as a whole. If not, then we're into the suggestion that being born in a particular month predisposes you to particular behaviours and that smacks of astrology, so I don't like it.

(Yes, I know there are other non-astrological factors which might be relevant, but let's give it a whirl, shall we?)



You're getting no tickyboxes for this, dammit, it's radio or nothing. I refuse to allow people to be born in more than one month.

Well, I just looked at the flatness of that righthand margin, and thought "nah..."

The sample isn't, of course, perfectly random: it includes all our staff, which probably is random, but also all our students for the past N years. For a single year, there are probably peculiarities introduced by the period of the academic year, simililar to the school year (eg. hypothetically, we could get fewer students who's birthday is late in the school year, as they decide to defer). I'm hoping that by simply hoovering many years, those boundary effects will cancel out.
