For inclusion into an index, two variables should have a strong bivariate relationship, meaning that they are positively correlated and move together in the same direction. A perfect relationship may not always be necessary as slight variations in correlation can still be useful in creating an index, but there should be a strong enough relationship to provide a meaningful measure of a certain phenomenon or concept. Weak, negative or no bivariate relationships are not suitable for inclusion in an index.
