... Measures of Center: Geometric Mean The geometric mean is used when the variable is a growth rate or rate of change, such as the value of an investment over periods of time. If Ri denotes the rate of return in period i (i = 1, 2, …, n), then The geometric mean Rg of the returns R1, R2, … Rn is defin ...
