Can't click on that
There are far more young than olds. Age is a pyramid. Bigger base/ smaller top. What we are looking for is something with a small SD that is also not a pyramid in structure. I.e.- lots of variation, and a fairly equal distribution of the variation
Edit: Look at the graph you posted turned vertically. It's essentially a pyramid; you just chose a visual that plots on a different axis. Google " age pyramid" or population pyramid ... http://www.indexmundi.com/united_states/age_structure.html

not if we assume that iq follows a normal distribution, because there are other traits which follow distributions which have higher likely spreads (e.g. age)
it also depends on how you're quantifying the difference. for example, how do you compare a difference in a numerical trait like age to a binary trait like gender.

weirdly worded q, random means you could get 2 equal IQ people?
if you're asking what single trait, all other things being equal, would cause the biggest difference in two different americans, obviously 70 iq/130 iq would probably be the biggest reasonable difference yea. otherwise, it's probably some geographic difference like coastal urbanite v. breadbasket farmer.
race would be a big one except there's very little difference between asians and white strivers, also hispanics and poor whites. obviously upper class asian and urban black would be the biggest.

income isn't normally distributed either. wealth distribution is even more extreme.
it'd be incredibly unlikely to draw two people at random where one has an IQ even 4x the other.
income even if you draw the top 10% against bottom 10% that's a massive relative difference. not even sure it'd make sense since the bottom of the income distribution without government assistance is 0. is a middle class person infinitely better off than a poor?
