Mr Brewin’s S1 – The Spirit Level

Mr Brewin — Mon, 24 Jan 2011 10:01:07 +0000

The slides I was talking about are embedded below. They are from a debate between the authors of The Spirit Level (you can buy it here) and their detractors (who have been shown to be wrong, and wanting to dispute the evidence for ideological reasons). The audio of the debate can be found here.

Update: here’s a pseudo-equation for working out the median:

Where LCB=Lower Class Boundary, CW= Class Width, M.obs is the observation where the median is going to be, UC.Obs is the Observation at the Upper Class and LC.Obs is the same for Lower Class. Confused? Thought you would be!

Hope that helps!

Sorry didn’t get to post this last night. The latest slides on interpolation etc. are here.

The answers to the exercises from Chapter 2 so far are here:
