Syntax

stddevc(listname,column[,ignore-nulls])

Description

Returns the standard deviation for a list column specified by listname and column. stddevc() can only be used with columns defined using variables so it cannot be used with lists defined from a SQL class

If you set ignore-nulls to 1, null values are ignored and not counted. If you omit this parameter or it evaluates to zero, nulls are treated as zero values and are counted.
