+        Return the mean of the values over the requested axis.
+
+        Parameters
+        ----------
+        axis : {index (0)}
+            Axis for the function to be applied on.
+            For `Series` this parameter is unused and defaults to 0.
+
+            For DataFrames, specifying ``axis=None`` will apply the aggregation
+            across both axes.

+            .. versionadded:: 2.0.0
+
+        skipna : bool, default True
+            Exclude NA/null values when computing the result.
+        numeric_only : bool, default False
+            Include only float, int, boolean columns.
+        **kwargs
+            Additional keyword arguments to be passed to the function.
+
+        Returns
+        -------
+        scalar or Series (if level specified)
+            Median of the values for the requested axis.
+
+        See Also
+        --------
+        numpy.median : Equivalent numpy function for computing median.
+        Series.sum : Sum of the values.
+        Series.median : Median of the values.
+        Series.std : Standard deviation of the values.
+        Series.var : Variance of the values.
+        Series.min : Minimum value.
+        Series.max : Maximum value.
+
+        Examples
+        --------
+        >>> s = pd.Series([1, 2, 3])
+        >>> s.mean()
