Chi-square distribution

Chi-square distribution

a distribution in which a variable is distributed like the sum of the the squares of any given independent random variable, each of which has a normal distribution with mean of zero and variance of one. The chi-square test is a statistical test based on comparison of a test statistic to a chi-square distribution. The oldest of these tests are used to detect whether two or more population distributions differ from one another.

Re: Brain size=IQ level theory (Blacks vs Whites & Asians)

Diffusion and concentration gradient

I think this is the result of neural regulation. Transport and the distribution of related molecules is completed under the control of the brain via some specific receptor proteins .

G.I. Problems from Antibiotic Use

There's not a lot of distribution from blood to the colonic lumen - it's virtually oxygen-free, the residents live on the contents and not systemic nutrients. I'm sure that some blood-carried materials get in there, but it's not a certainty.
