float stdevp(float data [, ...])

Returns the actual ("biased") standard deviation of the arguments, regarded as a complete population. If the argument list contains a sample of a larger population for which the standard deviation is to be estimated, use stdev instead.

All elements in the argument list are converted to floats, with exclusion if conversion fails. The list may contain array arguments, in which case each array element is treated as a separate list element.

Equivalent to sqrt(varp(data [, ...])).

Example

The expression

=stdevp(1, 7, 2, 5, 0, 3, 6, 6, 8, 3)

returns 2.5475478405714.
