Formula and methodology
Formula: Sample SE=s/√n; relative standard error=SE/|mean|; percentage RSE=100×RSE.
RSE scales the estimated standard error by the magnitude of the estimate, which helps compare relative precision across measures with different units or sizes.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Sample values — Comma-separated numeric observations.
Worked example
| Input | Value |
|---|---|
| Sample values | 10, 12, 9, 11, 8 |
Mean = 10; standard error ≈ 0.7071; relative standard error ≈ 7.071%.
Assumptions and limits
- At least two finite observations are supplied and the sample mean is nonzero.
- The sample standard deviation uses the N−1 divisor.
- Relative error is not meaningful when the estimate is near zero and should not replace an uncertainty analysis.
