Calculate the geometric mean (central tendency for multiplicative data)

About Geometric Mean

The geometric mean is the nth root of the product of n numbers. It is used for data that is multiplicative in nature.

Formula: GM = (x₁ × x₂ × ... × xₙ)^(1/n)

Best Used For:

  • Growth rates and ratios
  • Investment returns over time
  • Biological population growth
  • Log-normally distributed data

Example: If an investment grows 10%, -5%, and 20% over three years, the geometric mean gives the equivalent constant growth rate.
