Using the same example as we did for the arithmetic mean the geometric mean calculation equals. An alternative way to write the formula is X1 x X2. The first step in calculating the Geometric Mean using this method is to determine the logarithm of each data point using your calculator.
Returns the geometric mean of an array or range of positive data.
In other words take the average of the logs. This formula is used in our calculator. In order to find the geometric mean multiply all of the values together before taking the n th root where n equals the total number of values in the set. Step 1 - Select type of frequency distribution Discrete or continuous Step 2 - Enter the Range or classes X seperated by comma.
