Well, god gave us Bayes' rule for a reason.
The article does not point out that sampling quora users might not be (I would say is probably not) an unbiased estimator of the the students of these places as a whole. Quora attracts a certain kind of person, I've never seen it mentioned anywhere outside of techy startup / valley circles. Maybe that's implied by virtue of it being in the HN ecosystem, but still it should be explicitly stated as a flaw in the method. Lies, damned lies and statistics etc.
- azylman 14y agoThe article does not point out that sampling quora users might not be (I would say is probably not) an unbiased estimator of the the students of these places as a whole. From the article: Also, a word of warning: my dataset was fairly small and users on Quora are almost certainly not representative of their schools as a whole (though I tried to be rigorous with what I had).
- ballooney 14y agoI completely missed that, mea culpa, my apologies to the author. I'll leave the message above unedited as a little warning sign to other people who can't read: you too can look silly like me.
