Corr

This function calculates the coefficient of correlation of a set of number pairs. It uses the following formula: Covar_Pop(Y, X)/(Stddev_Pop(Y) * Stddev_Pop(X)). The pairs where Y or X is NULL are discarded.

Syntax:

Corr(Y, X)

Parameters:

• Y. Type: Number.
• X. Type: Number.

Example:

X	Y
1	7
2	1
3	2
4	5
5	7
6	34
7	32
8	43
9	87

SELECT Corr(X, Y) FROM Table
