Formula and methodology
Formula: g₁=[Σ(xᵢ−x̄)³/n]/s³, with s using the population divisor n for this coefficient.
Positive skewness indicates a longer right tail in this convention; negative skewness indicates a longer left tail.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Data values — Comma-separated numeric observations.
Worked example
| Input | Value |
|---|---|
| Data values | 1, 2, 2, 3, 10 |
Population skewness ≈ 1.361.
Assumptions and limits
- The values are finite quantitative observations.
- This is the unadjusted Fisher-Pearson population-moment coefficient, not a small-sample adjusted estimator.
- Skewness near zero does not prove normality or symmetry in a small sample.
