PEARSON

See Also

Returns the Pearson product moment correlation coefficient, r, a dimensionless index that ranges from -1.0 to 1.0 inclusive and reflects the extent of a linear relationship between two data sets.

Syntax

PEARSON(array1,array2)

Array1 is a set of independent values.

Array2 is a set of dependent values.

Remarks

The arguments must be either numbers or names, array constants, or references that contain numbers.
If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included.
If array1 and array2 are empty or have a different number of data points, PEARSON returns the #N/A error value.
The r value of the regression line is:
