Correlation is a technique that summarizes the relationship between 2 paired variables. The technique gives one number, the correlation coefficient, that expresses whether “higher” numbers in one variable tend to be paired with “higher” numbers in the other variable (a positive correlation), or whether “higher” numbers in one variable are associated with “lower” numbers in the second variable (a negative correlation).
