In mathematics the geometric mean of a group of n numbers is found by taking the n th root of the product of the numbers. So the geometric mean gives us a way of finding a value in between widely different values. That is the geometric mean of a1a2a3an a 1 a 2 a.
Another way to calculate the geometric mean is with logarithms as it is also the average of logarithmic values converted back to base 10.
It is handy to use log with base 2 here so 2 2 1 and 8 2 3. Find 1 N 1 N 1 5 02 Step 2. The general formula for the geometric mean of n numbers is the nth root of their product. Another way to calculate the geometric mean is with logarithms as it is also the average of logarithmic values converted back to base 10.
