While lesser known than the arithmetic mean, the geometric mean is an important calculation often used by scientists, biologists, and in financial reporting. The geometric mean is calculated by multiplying a set of numbers and taking the nth root, where n represents the total number of values in the sample. If that sounds like a mouthful, it can be simplified by thinking of it as the average of the logarithmic values converted into a base 10 number.
