The formula for evaluating geometric mean is as follows if we have n number of observations. Another way to calculate the geometric mean is with logarithms as it is also the average of logarithmic values converted back to base 10. Using the same example as we did for the arithmetic mean the geometric mean calculation equals.
How to Calculate the Geometric Mean In order to calculate Geometric Mean we multiply the given numbers altogether and then take a square root given that there are two numbers or cube root for three numbers 5th root for five numbers etc.
For n numbers present to calculate the geometric mean formula all the numbers are multiplied together and then the n th root of the same is taken. Find the geometric mean of the. 1 to 255 arguments for which you want to calculate the mean. Which is 16 millimeters or about the thickness of a coin.
