Log geometric mean formula
The logarithmic mean is the mean is obtained by dividing the sum of the logarithm of n numbers by their count.
\(\displaystyle log(G) =\frac{1}{n} · (log(x_1) + log(x_2) + ... + log(x_n)) \)
Example
\(\displaystyle log(G) =\frac{1}{3} · (log(7) + log(9) + log(12)) \)
\(\displaystyle =\frac{1}{3} · (1.95 + 2.2 + 2.48) \)
\(\displaystyle =\frac{1}{3} · (6.63) = 2.21 \)
