1400 rectangles from Dan Meyer. I just wanted to look at it this way.
I hate how big the default dots in excel (or clones) are. They seem designed for looking at very small amounts of data.
The rectangle drawing may have been heavily influenced by the size of the window that the dots were drawn on.
@Mr K – I agree. I was about to redo it with smaller, lighter dots and decided I’d given too much time to this already.
@gswp: There’s a rich discussion on this and other sampling/experimental design issues at Dan Meyer’s original page (maybe you’ve already contributed there – I haven’t tracked it carefully)
Oh! I just saw that my link to the original page didn’t show up in my original post – that’s been fixed above, or click here.
Can you remind me (us?) where this sort of crowdsourcing accuracy theory comes from? I know that this is something I have read on in the past but my brain cannot find an accurate reference. I know that there is a theory that if you ask a large enough sample of people to estimate something, say the population of Fargo, ND then the average guess will be fairly accurate. I have to assume this is what Dan M is getting at but I don’t remember the source of this idea.
@Jim – No idea. You might post your question on Dan Meyer’s page if you haven’t already.
I just learned how to close comments in WordPress and I think I’ll close these – I don’t have any knowledge to add here and it’ll be more fun if we all join the fray on Dan M’s page.
