Geometric Mean in Python
import numpy as np
from scipy.stats import gmean
Example 1 Manual
data = [4, 7, 3, 8, 2, 1, 5]
n = len(data)
product = 1
for x in data:
product *= x
geometric_mean = product ** (1/n)
print(geometric_mean)
Example 2 Numpy
product_np = np.prod(data)
result_numpy = np.power(product_np, 1/n)
print(result_numpy)
Example 3 Scipy
result_scipy = gmean(data)
print(result_scipy)
Example 4 Scipy Percentages Growth Rate
Growth Rate
percentages = [10, 15, 20, -5]
decimal_values = [(1 + p / 100) for p in percentages]
geometric_mean_decimal = gmean(decimal_values)
geometric_mean_decimal
geometric_mean_percentage = (geometric_mean_decimal - 1) * 100
geometric_mean_percentage
