Correlation does not imply cause and effect.Sales of rum and number of Methodist ministers is positively correlated, but a large number of ministers does not encourage rum drinking.Is there a third variable that influences both rum sales and Methodist ministers?
An example of a strong negative correlation would be -0.97. The variables would move in opposite directions in a nearly identical move. The values demonstrate the strength of a relationship as the numbers approach 1 or -1. Numbers of 0.92 or -0.97 would show a strong positive and negative c...
Correlation does not imply causation, as the saying goes, and the Pearson coefficient cannot determine whether one of the correlated variables is dependent on the other. Nor does the correlation coefficient show what proportion of the variation in the dependent variable is attributable to the independ...
