Formula
geometricMean = (x1×x2×...×xn)^(1/n)
Where:
- numbers=Numbers (comma-separated)
Worked Examples
Three values
Find geometric mean of 2, 8, 32.
- 1Product = 2×8×32 = 512
- 2n=3
- 3Cube root of 512 is 8
Two values
Find geometric mean of 4 and 9.
- 1Product = 36
- 2n=2
- 3Square root of 36 is 6
Decimal inputs
Find geometric mean of 1.5, 6, 24.
- 1Product = 216
- 2n=3
- 3Cube root is 6
Introduction
Geometric mean is ideal for multiplicative processes such as growth rates, ratios, and normalized index comparisons.
Formula and Method
Geometric Mean Calculator applies geometricMean = (x1×x2×...×xn)^(1/n) and returns deterministic outputs from validated inputs.
Validate each required input
Apply the stated formula
Round numeric outputs where needed
Return safe defaults when validation fails
Input Fields
Use these keys exactly as defined in calculation.ts.
- 1
numbers: Numbers (comma-separated)
Output Fields
These values map directly to calculation.ts return keys.
- 1
geometricMean: nth root of the product of all inputs
- 2
count: Number of valid values used
Validation Rules
Input must parse into one or more positive finite numbers.
Finite numeric values are required
Domain restrictions are enforced before solving
Invalid input returns default-safe outputs
Check examples to confirm expected behavior

FAQs
What does the Geometric Mean Calculator compute?
It computes Geometric Mean and supporting outputs from your inputs.
Which inputs are required?
Required inputs are: Numbers (comma-separated).
How are invalid inputs handled?
When validation fails, the calculator returns safe default values and does not attempt invalid math.
Are results rounded?
Yes. Numeric outputs are rounded inside calculation.ts (typically to 6 decimal places).
Can I use negative or decimal values?
Only positive numbers are valid because negative/zero values break real geometric-mean assumptions.
How should I verify my answer?
Use the worked examples and compare each output key with your manual steps.
