A Paul Krugman "oops" moment that is genuinely funny...



Now, obviously, six or seven Canadians watching Paul Krugman is not a scientific survey. There are 33.2 million Canadians, so seven people would not make a legitimate sample, would it? [That would be a sample size of .000002%]

On the other hand, if you called up 527 self-identified Republicans nationwide, and only 221 of them said they were sure that Barack Obama was born in the United States, would that entitle you to say that 58% of all GOPers are potential birthers?

Well, let's see: there are roughly 55 million Republicans in the US, so that would be a sample size of .000095%, which is an order of magnitude larger but hardly conclusive.

Anyway, the Krugman video is funny in inconsequential, and only 34 seconds long.

ACtually, it is TWO orders of magnitude larger. But it is not the size of the sample so much as the randomness in question.
