- 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*.
