WebGeometric Mean Calculation How do you calculate a geometric mean? The easiest way to think of the geometric mean is that it is the average of the logarithmic values, converted back to a base 10 number. However, the actual formula and definition of the geometric mean is that it is the n-th root of the product of n numbers, or: WebAs for excluding zeroes, the geometric mean is undefined for non-positive values, including zeroes. The above is a common fix for geometric mean, in which zeroes (or in this case all non-zeroes) are given a dummy value of 1, which has no effect on the product (or equivalently, zero in the logarithmic sum).
WebThe geometric mean can be understood in terms of geometry. The geometric mean of two numbers, and , is the length of one side of a square whose area is equal to the area of a rectangle with sides of lengths and .
