# stddevSamp {#stddevsamp}
The result is equal to the square root of [varSamp](../../../sql-reference/aggregate-functions/reference/varsamp.md).
!!! note "Note"
This function uses a numerically unstable algorithm. If you need [numerical stability](https://en.wikipedia.org/wiki/Numerical_stability) in calculations, use the `stddevSampStable` function. It works slower but provides a lower computational error.
