pandas.Series.std¶
- 
Series.std(self, axis=None, skipna=None, level=None, ddof=1, numeric_only=None, **kwargs)[source]¶
- Return sample standard deviation over requested axis. - Normalized by N-1 by default. This can be changed using the ddof argument - Parameters: - axis : {index (0)}
- skipna : bool, default True
- Exclude NA/null values. If an entire row/column is NA, the result will be NA 
- level : int or level name, default None
- If the axis is a MultiIndex (hierarchical), count along a particular level, collapsing into a scalar 
- ddof : int, default 1
- Delta Degrees of Freedom. The divisor used in calculations is N - ddof, where N represents the number of elements. 
- numeric_only : bool, default None
- Include only float, int, boolean columns. If None, will attempt to use everything, then use only numeric data. Not implemented for Series. 
 - Returns: - scalar or Series (if level specified)
