# cudf.DataFrame.quantile#

DataFrame.quantile(q=0.5, axis=0, numeric_only=True, interpolation='linear', columns=None, exact=True)#

Return values at the given quantile.

Parameters
qfloat or array-like

0 <= q <= 1, the quantile(s) to compute

axisint

axis is a NON-FUNCTIONAL parameter

numeric_onlybool, default True

If False, the quantile of datetime and timedelta data will be computed as well.

interpolation{linear, lower, higher, midpoint, nearest}

This parameter specifies the interpolation method to use, when the desired quantile lies between two data points i and j. Default `linear`.

columnslist of str

List of column names to include.

exactboolean

Whether to use approximate or exact quantile algorithm.

Returns
Series or DataFrame

If q is an array or numeric_only is set to False, a DataFrame will be returned where index is q, the columns are the columns of self, and the values are the quantile.

If q is a float, a Series will be returned where the index is the columns of self and the values are the quantiles.

Pandas Compatibility Note

DataFrame.quantile

One notable difference from Pandas is when DataFrame is of non-numeric types and result is expected to be a Series in case of Pandas. cuDF will return a DataFrame as it doesn’t support mixed types under Series.

Examples

```>>> import cupy as cp
>>> import cudf
>>> df = cudf.DataFrame(cp.array([[1, 1], [2, 10], [3, 100], [4, 100]]),
...                   columns=['a', 'b'])
>>> df
a    b
0  1    1
1  2   10
2  3  100
3  4  100
>>> df.quantile(0.1)
a    1.3
b    3.7
Name: 0.1, dtype: float64
>>> df.quantile([.1, .5])
a     b
0.1  1.3   3.7
0.5  2.5  55.0
```
