Geometric mean is defined as the nth root product of n numbers. It is an average which gives the mean or central value of a given set of numbers, using the product of the values. The geometric mean canāt be calculated using arithmetic mean.
where, n is the total number of observations.
Example: Find the geometric mean of 8 and 9.
Geometric Mean = ā(8 x 9)
= 2×3ā2
G.M = 8.48
