Geometric Mean. The Geometric Mean is a special type of average where we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc. First we multiply them: 2 Ã 18 = 36. Then (as there are two numbers) take the square root: â36 = 6.
Geometric Mean Definition: Geometric mean is a kind of average of a set of numbers that is different from the arithmetic average. The geometric mean is well defined only for sets of positive real numbers.This is calculated by multiplying all the numbers (call the number of numbers n), and taking the nth root of the total.A common example of where the geometric mean is the correct choice is when averaging growth rates.Geometric Mean = ((X1)(X2)(X3)........(XN))1/N.his is calculated by multiplying all the numbers (call the number of numbers n), and taking the nth root of the total.
