  • CORREL

    CORREL

    Returns the correlation coefficient of the array1 and array2 cell ranges. Use the correlation coefficient to determine the relationship between two properties. For example, you can examine the relationship between a location's average temperature and the use of air conditioners.

    Syntax

    CORREL(array1,array2)

    Array1     is a cell range of values.

    Array2     is a second cell range of values.

    Remarks

    • 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 have a different number of data points, CORREL returns the #N/A error value.
    • If either array1 or array2 is empty, or if s (the standard deviation) of their values equals zero, CORREL returns the #DIV/0! error value.
    • The equation for the correlation coefficient is:

    Equation

    where

    x and y

    are the sample means AVERAGE(array1) and AVERAGE(array2).

    Example

    The example may be easier to understand if you copy it to a blank worksheet.
