PEARSON

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:

  

Example

PEARSON({9,7,5,3,1},{10,6,1,5,3}) equals 0.699379
