Date: April 22nd, 2017 10:24 AM Author: Angry stag film This is almost certainly incorrect; age disribition is a pyramid.

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 |

Date: April 22nd, 2017 10:06 AM Author: cheese-eating clown dilemma 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. |

Date: April 22nd, 2017 2:50 PM Author: Excitant chad except for the part where they convert from a raw score to a scaled score, so they pretty much get to decide on the distribution. they norm it on a large enough sample that they pretty much know how people are going to do.
of course the scores are roughly normally distributed anyway, that's why they don't use some other distribution instead. |

Date: April 22nd, 2017 2:52 PM Author: Electric casino sure but a histogram of questions answered correctly would have an even tighter numerical distribution. at the upper and lower ends of IQ scores, just a few questions can move you by a standard deviation.

Date: April 22nd, 2017 10:09 AM Author: Angry stag film Disagree. Bell curve and all - most people cluster around the mean IQ of 100. This is also true for most biometric markers. Best to pick something without as tight of a mean cluster if you want to improve your odds of big differences between two randoms. Age is a good one

Date: April 22nd, 2017 10:12 AM Author: Angry stag film Where my reasoning breaks down is comparing whether there is greater statistical likelihood of a difference in something binary ( like gender or political orientation) vs something mean clustered.

Date: April 22nd, 2017 10:22 AM Author: Angry stag film Also hard to quantify racial difference. Is the difference between a black vs a white person greater or equal to an Asian vs White person? And is the difference between either greater than the difference between a 100 vs 115 IQ? IQ, age, height, etc., at least are quantifiable and you can argue that the greater the SD, the bigger the difference. " Race" is pretty vague in that regard (http://www.autoadmit.com/thread.php?thread_id=3592014&forum_id=2#33133503) |

Date: April 22nd, 2017 10:28 AM Author: Greedy Locale 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. |

|
Date: April 22nd, 2017 10:43 AM Author: Greedy Locale I mean if the question is really a probability one like asked, then iq can't be the biggest difference because of the bell curve - picking two random people means your highest chances are of picking 2 100-iq people and fans out from there. Same thing with race though to a lesser degree - most Americans are white, blacks are only like 10% - so the highest likelihood is white-white. Same thing with urban/rural because something like 75% of the country lives in urban areas.
The answer would probably be sex then, given that half the time you get a pretty meaningless same-sex pairing but half the time you get an opposite-sex pairing. Men and women are very different - you might get bigger differences between black poor and rich asian, or 140-iq versus 60-iq, but because the probability of that pairing coming up is so low you're better off just picking sex. |

|
Date: April 22nd, 2017 2:48 PM Author: Electric casino 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? |
