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 lawNow 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?
