Correlation

(Science: statistics) most generally, the degree to which one phenomenon or random variable is associated with or can be predicted from another.

in statistics, correlation usually refers to the degree to which a linear predictive relationship exists between random variables, as measured by a correlation coefficient. Correlation may be positive, i.e., both variables increase or decrease together or negative or inverse, i.e., one variable increases when the other decreases.

Re: human brain size

... over the past 28,000 years), a friend of mine claims that the potential intellectual capacities of mankind have gone down (because there is a correlation between brain size and intelligence). This seems very counterintuitive to me, but I couldn't find any facts or arguments to prove the opposite. ...

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

I think there is no correlation between brain size and IQ level. If compare brains of whale and elephant with humans, ours is too small. But we have very high intelligence. I think some connections between neurons or some unknown factors ...

Re: Western transfer failure

... gel transferred fine, another went backwards to blot paper after 1 hr. Did I just arrange backwards? Did lack of SDS mess with electric gradient? Correlation may not be causation, so I don't claim lack of SDS was the problem. It would be easy to do an experiment, though.

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

... body mass. We can more-or-less see that in human evolution, and we see it in primates other than humans, and we see it in mammals generally. The correlation between brain size and intelligence is extremely weak. Nevertheless, there is absolutely no evidence that black people have smaller brains ...
