Geometric mean calculator is an online tool to find the geometric mean of a given date. It is different from the sample mean. The expression for the geometric mean is given below.


Where $a_{1}$, $a_{2}$, $a_{3}$ are the observations
          n is the number of observations
Following steps are used for the geometric mean calculation.

Step1: Multiply all given observations.

Step2: Find the nth root of this value, where n is the total number of observations.
