What is geometric mean - Definition and Meaning

Geometric Mean :

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 , and taking the nth root of the total. A common example where the geometric mean is the correct choice is when averaging growth rates.

Example :

To find the Geometric Mean of 1,2,3,4,5. Step 1: N = 5, the total number of values. Find 1/N. 1/N = 0.2 Step 2: Now find Geometric Mean using the formula. (1*2*3*4*5)0.2 = (120)0.2 Geometric Mean = 2.60517
