Academic? Ummm,... how a statistician slices a pizza 10 ways?

Hmmm. I read that in aggregates of numbers that occur in the real world: Say, a tax declaration, a bank balance, a collection of measurments, the ten digits, 0-9, occur in a non-random fashion: 1 is the most freuquent, and the others follow, decreasing in frequency as digits grow larger. It's rather counter-intuitive, but it grows clearer as you dive into it.

Ah, here it is: Benfords law

Now if, as in the graph you presented, the digits occur in almost euqal quantities (as they do in your graph), then the conclusion is that the numbers have been tampered with. They are TOO random when they shouldn't be.

So maybe these are the collected and counted digits from someone's tax declaration? Clinton's? Trump's?

You may be on the right track but I'll remind you that this is nothing political.

ETA: And nothing has been manipulated.

The graph represents that actual distribution of digits of something. What?

Maybe I should add that Benford's law applies to leading digits in such numbers, not all the digits.

The distribution in the graph looks as if it varies, pretty randomly, around 1,000. Every digit appears with approximately the same probability (within 5% of the average,). Also, the ten numbers/digits add up to exactly 10.000. That must be a clues I am not getting.

Shucks, yeah, that must be it. Random, indeed.

Not surprised... It's the frequency of digits in Pi to 10,000 places.

It's from here, part way down: Ben Greenman’s Museum of Silly Charts.

And I'm sorry if I disappointed anyone by avoiding anything about penises or labias.

That was a nice read.

Well, maybe I can crack Mactep's next one. We seem to be the only ones here really in for charts, right?

Maybe someone should graph the most to least active participants in this thread for the past year.

Here's one to keep us occupied for the time being.

I knew I was supposed to put something here. I didn't realise just how long it had been . . .

Not sure what the above graph is.

An analysis of Moscow hookers by Ruble/litre? Or would that be a flow chart?

I think we can give it to Heid just for that one. Or does anyone have any idea what the graph could otherwise show?

I want to give it to Heid on style points alone!

But it's very different.

I think it is yours. Lance wanted to give it to me but didn't. That and my inability to find or post graphs.

It's actually still Mactep's, but while we wait, Arneb has the next move in our "sub-game".
