Geometric standard deviation
The geometric standard deviation (often abbreviated to GSD ) is a measure of the spread of the deviations from the geometric mean .
In general, it is calculated as follows:
with the geometric mean :
In contrast to the arithmetic standard deviation , the product and not the sum is interpreted here.
This statistical figure is mainly used in the natural sciences .
