CORREL

This function returns the correlation coefficient of the two sets of data.

CORREL(array1,array2)

The two arrays of data in the arguments of this function should meet these criteria:

The data should contain numbers, names, ranges, or references that are numeric. If some cells do not contain numeric data, they are ignored.
The arrays should be the same size, with the same number of data points.
The arrays should not be empty, nor should the standard deviation of their values equal zero.

Accepts arrays of numeric data for both arguments. Returns numeric data.

CORREL(C1:C10,D1:D10)

CORREL(R1C3:R10C3,R1C4:R10C4)

CORREL({5,10,15,20,25},{4,8,16,32,64}) gives the result 0.9332565253

CORREL({73000,45000,40360},{42,70,40}) gives the result -0.3261046660
