Spearman Command

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.
