Rank Correlation
In statistics, the extent to which two rankings match each other. There are various systems to calculate rank correlation. However, rank correlation is expressed on a scale from -1 to +1. A measure of -1 indicates the rankings disagree perfectly (meaning they are opposite one another), while a measure of +1 means they agree perfectly (meaning they are the same). A measure of 0 means the rankings are independent of one another.
