Formula
Adjusted Fisher–Pearson skewness G₁=n/[(n−1)(n−2)] × Σ[(x−mean)/s]³
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Uses the adjusted Fisher–Pearson sample coefficient; other skewness definitions differ.

Frequently asked questions
How do I use this calculator?
Enter data. The result updates automatically. Use Reset to restore the example values.
What method does it use?
Adjusted Fisher–Pearson skewness G₁=n/[(n−1)(n−2)] × Σ[(x−mean)/s]³. Uses the adjusted Fisher–Pearson sample coefficient; other skewness definitions differ.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
