Down On The Upside

I stumbled across the wonderful skepticalscience.com website last night (via Ken Rice‘s Twitter feed) and just had to quickly blog about this brilliant, at-a-glance rebuttal of that hoary old “The data don’t lie” aphorism. The graph speaks for itself…

 “But Philip, I thought you’d sworn off Twitter?” I have — I killed my Twitter account almost four years ago and have not once regretted it since. For one thing, a Twitter account is not required in order to read tweets and I occasionally dip into the Twitter threads of colleagues and friends I used to follow (Ken among them) via search.twitter.com.

An avid fan writes…

This arrived in my mailroom pigeonhole today — a proper, honest to goodness, old-school letter (but, disappointingly, written in boring monochrome rather than the traditional green.) It’s a response, of sorts, to my recent letter to The Sunday Times. I can’t quite decide as to whether it’s a pitch-perfect parody — the line about girls not instinctively “learning to throw” is perhaps a little too good — or if my aggrieved correspondent somehow joined Jacob Rees-Mogg in teleporting here from the 18th century…

In the Dark

So there’s an article in Scientific American called How to Close the Gender Gap in the Labo(u)r Force (I’ve added a `u’ to `Labour’ so that it can be understood in the UK).

I was just thinking the other day that it’s been a while since I added any posts to the `Bad Statistics’ folder, but this Scientific American article offers a corker:

That parabola is a  `Regression line’? Seriously? Someone needs to a lesson in how not to over-fit data! It’s plausible that the orange curve might be the best-fitting parabola to the blue points, but that doesn’t mean that it provides a sensible description of the data…

I can see a man walking a dog in the pattern of points to the top right: can I get this observation published in Scientific American?
