Correlation is a statistical measure that shows the relationship between two objects. Correlation may range between +1 and -1. If correlation between the objects is 0 that means they are not dependable on each other. If correlation is negative, that means they move in different directions, while +1 correlation would mean that fluctuations are identical.
