Correlation

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.

There is rather good correlation between UV (UVA,UVB and UVC) high radiation and dark skin color. However hair and facial differences are interesting issues too. Haven't ...
