Returns the geometric mean of a list of numbers.
float geometric_mean = llListStatistics( LIST_STAT_GEOMETRIC_MEAN, numList );
For two numbers, a and b, the geometric mean is llSqrt(a*b). For a list of n numbers, the geometric mean is the n-th root of their product. It indicates the central tendency or typical value to expect. It only works for positive numbers.
In comparison, the arithmetic mean (known as the average) is the sum of the numbers divided by how many numbers there are.
