Spearman[ <List of Points> ]
Returns Spearman's rank correlation coefficient of x-coordinates and y-coordinates of points of a list.
Example: Let list = { (-3, 4), (-1, 4), (-2, 3), (1, 3), (2, 2), (1, 5) } be a list of points. Spearman[ list ] yields a = -0.37.


Spearman[ <List of Numbers>, <List of Numbers> ]
Returns Spearman's rank correlation coefficient of two lists.
Example: Let list1 = {3, 2, 4, 5, 1, 6, 8, 9} and list2 = {5, 6, 8, 2, 1, 3, 4, 7} be two lists. Spearman[ list1, list2 ] yields a = 0.24.
