Calculations are computed using arbitrary-precision mathematical logic within browser memory, ensuring rapid and completely private computation.
Frequently Asked Questions
What is the difference between sample and population standard deviation?
Sample standard deviation uses Bessel correction (N - 1) for dataset samples, while population standard deviation divides by N for complete populations.
