Frequently asked questions
- Do I need to sign up?
- No. The tool works without an account.
- Are my data uploaded?
- Compatible operations run locally in the browser.
- What is the mean absolute deviation (MAD)?
- MAD = (1/n) * Σ |x_i - μ| where μ is the arithmetic mean. It measures average distance from the mean using absolute values, less sensitive to outliers than standard deviation.
- How does MAD differ from standard deviation?
- Standard deviation uses squared differences (more weight to large deviations). MAD uses absolute differences and is more robust to outliers.
