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.
