Geometric Mean

The geometric mean   of numbers is defined as the th root of the product of numbers .It is obtained by multiplying all the values of a variable and then extracting nth root of the product. Symbolically,

 G.M. =√(X1)(X2)..............(x4)

Where means the various values in the variable and n=number of items.

In order to facilitate calculation, logarithms are used in calculation .Using logarithms the following formula is used for its calculation;
