WebYour code has a couple of problems. First, you need to multiply values to get a geometric mean. Then, simply calling Math.pow will not change the value; it returns a new value that you must capture. For example: sum = Math.pow (sum, 1.0 / data.length); Share. Improve this answer.

Web29 mrt. 2024 · The formula of the gemetric mean is: So you can easily write an algorithm like: import numpy as np def geo_mean (iterable): a = np.array (iterable) return a.prod ()** (1.0/len (a)) You do not have to use numpy for that, but it tends to perform operations on arrays faster than Python. See this answer for why. There are two main steps to calculating the geometric mean: 1. Multiply all values together to get their product. 2. Find the nth root of the product (nis the number of values). Before calculating this measure of central tendency, note that: 1.
