db.models.StdDev.sample

sample

By default, StdDev returns the population standard deviation. However, if sample=True, the return value will be the sample standard deviation.

SQLite

SQLite doesn’t provide StdDev out of the box. An implementation is available as an extension module for SQLite. Consult the SQlite documentation for instructions on obtaining and installing this extension.
