(12C) Geometric Mean with Percentage

[Thomas Klemm]

You could just add 100 to the percentages, calculate the geometric mean and subtract 100 from the result.

Also the logarithm could be used to translate the geometric to the arithmetic mean:

\(
\log(\sqrt{x \cdot y}) = \frac{\log{x} + \log{y}}{2}
\)

This program enters the data:

Code:

01-       26 : EEX
02-        2 : 2
03-       40 : +
04-    43 23 : g LN
05-       49 : Σ+

To calculate the geometric mean use:

Code:

01-    43  0 : g x̄
02-    43 22 : g eˣ
03-       26 : EEX
04-        2 : 2
05-       30 : -
