Coefficient of correlation
Coefficient of correlation is a mathematical figure for showing the degree of agreement or uniformity of relationship between two things, groups, sets of facts or series of data or certain qualities thereof. A perfect agreement or uniformity of relationship is unity, or one. Consequently, the nearer the coefficient of correlation is to one, the closer is the agreement or uniformity of relationship for the two matters under consideration.
