For example, a different mean, called the geometric mean (G.M.), is used in business and economics for finding average rates of change, average rat growth, or average ratios. This mean is defined to be the nth root of the product of the numbers. For example, the geometric mean of 4, 5, and 6 is G.M. = (4 · 5 · 6)/3 V120 z 4.9.
