GEOMEAN

Category:

Statistical Analysis

Summary:

Calculates the geometric mean of a set of numbers. The geometric mean of a set of N numbers is the Nth root of the product of the numbers.

Syntax:

GEOMEAN(Number 1 [; Number 2 [; … [; Number 255]]])

Returns:

Returns a non-negative real number which is the geometric mean of the set of numbers.

Arguments:

Number 1, Number 2, ..., Number 255 are numbers, references to cells or to cell ranges of numbers for which the geometric mean is to be calculated.

• If any of the arguments contain a value less than zero then the function returns an error value. However, empty cells and those with non-numeric (except for logical) values are ignored.

• The formula for GEOMEAN is:

where N is the set of numbers passed as arguments and n is the size of that set. To find the value of n, use the function COUNT(N).

Formula Description Returns
=GEOMEAN(23.5;46.7;69.5;4.54) The function calculates the geometric mean of the arguments passed. 24.2580758724851
=GEOMEAN(A1:A5) where A1:A5 contains 1,2,3,4,5 respectively The function calculates the geometric mean of the arguments passed. 2.60517108469735
=GEOMEAN(A1:A5) where A1:A5 contains 1,2,-3,4,5 respectively The function returns an error value since one of the arguments passed contains a negative value. Err:502
