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)

... and so on. Big hint: if it didn't happen in nature, it ain't gonna happen among humans. Humans are just one example. Just look at the geographic distribution of other native animals, even virus, such as that causing AIDS. This is totally irrelevant to the topic. Nobody's arguing that there aren't ...

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 .
