Geometric mean how to calculate
WebThe resultant geometric mean, in this case, will be 25.90%. This is much lower than the Arithmetic mean of 41.25%. Recommended Articles. This article has been a guide to Geometric Mean and its definition. Here we discuss the formula of Geometric Mean Return along with examples and excel templates. 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).
