DataFrame.skew(axis: Union[int, str, None] = None, skipna: bool = True, numeric_only: bool = None) → Union[int, float, bool, str, bytes, decimal.Decimal,, datetime.datetime, None, Series]

Return unbiased skew normalized by N-1.

axis: {index (0), columns (1)}

Axis for the function to be applied on.

skipna: bool, default True

Exclude NA/null values when computing the result.

Changed in version 3.4.0: Supported including NA/null values.

numeric_only: bool, default None

Include only float, int, boolean columns. False is not supported. This parameter is mainly for pandas compatibility.

skew: scalar for a Series, and a Series for a DataFrame.


>>> df = ps.DataFrame({'a': [1, 2, 3, np.nan], 'b': [0.1, 0.2, 0.3, np.nan]},
...                   columns=['a', 'b'])

On a DataFrame:

>>> df.skew()
a    0.0
b    0.0
dtype: float64

On a Series:

>>> df['a'].skew()
