# xarray.Variable.median

#### Variable.median(dim=None, , skipna=None, \*\*kwargs)[[source]](https://github.com/pydata/xarray/blob/main/xarray/namedarray/_aggregations.py#L710-L777)

Reduce this NamedArray’s data by applying `median` along some dimension(s).

* **Parameters:**
  * **dim** ([`str`](https://docs.python.org/3/builtins/stdtypes.html#str), `Iterable` of `Hashable`, `"..."` or [`None`](https://docs.python.org/3/builtins/constants.html#None), *default*: [`None`](https://docs.python.org/3/builtins/constants.html#None)) – Name of dimension[s] along which to apply `median`. For e.g. `dim="x"`
    or `dim=["x", "y"]`. If “…” or None, will reduce over all dimensions.
  * **skipna** ([`bool`](https://docs.python.org/3/builtins/functions.html#bool) or [`None`](https://docs.python.org/3/builtins/constants.html#None), *optional*) – If True, skip missing values (as marked by NaN). By default, only
    skips missing values for float dtypes; other dtypes either do not
    have a sentinel missing value (int) or `skipna=True` has not been
    implemented (object, datetime64 or timedelta64).
  * **\*\*kwargs** (`Any`) – Additional keyword arguments passed on to the appropriate array
    function for calculating `median` on this object’s data.
    These could include dask-specific kwargs like `split_every`.
* **Returns:**
  **reduced** (`NamedArray`) – New NamedArray with `median` applied to its data and the
  indicated dimension(s) removed

### Notes

Non-numeric variables will be removed prior to reducing. datetime64 and timedelta64 dtypes are treated as numeric for aggregation operations.

```pycon
>>> from xarray.namedarray.core import NamedArray
>>> na = NamedArray("x", np.array([1, 2, 3, 0, 2, np.nan]))
>>> na
<xarray.NamedArray (x: 6)> Size: 48B
array([ 1.,  2.,  3.,  0.,  2., nan])
```

```pycon
>>> na.median()
<xarray.NamedArray ()> Size: 8B
array(2.)
```

Use `skipna` to control whether NaNs are ignored.

```pycon
>>> na.median(skipna=False)
<xarray.NamedArray ()> Size: 8B
array(nan)
```
