LaTeX
G=\left(\prod_{i=1}^{n}x_i\right)^{1/n}Variables
- xᵢ: positive values
- n: count
How to use this formula
Averages positive values multiplicatively.
Important notes
- Useful for growth rates and ratios.
Quick example
Geometric mean of 2 and 8 is 4.
Applicability, worked calculation, and verification
Assumptions and domain checks
- Useful for growth rates and ratios.
- For the Geometric Mean, every denominator must be nonzero, and the numerator and denominator must remain correctly grouped.
- For the Geometric Mean, the index variable, lower bound, upper bound, and any empty-sum or empty-product convention must be clear.
- For the Geometric Mean, identify whether each quantity is a sample statistic, population parameter, estimator, or model value, and check the method assumptions.
Worked example
Geometric mean of 2 and 8 is 4.
Common mistakes
- Do not omit the index or bounds in Geometric Mean; changing either one changes which terms are included.
- For the Geometric Mean, do not interpret a descriptive statistic as a causal or population conclusion without the sampling and model assumptions.
