Standard Deviation Calculator

1. Data Input: Enter your data points.
2. Type: The tool usually displays both Sample and Population results.
3. Analyze: Check variance and standard deviation to understand data volatility.

The Standard Deviation Calculator measures the amount of variation or dispersion in a set of values. A low standard deviation indicates values are close to the mean; a high one means they are spread out.

This tool calculates both Population (σ) and Sample (s) standard deviation, which use slightly different formulas.
