polars.Series.quantile

Series.quantile(
    quantile: float | list_[float],
    interpolation: QuantileMethod = 'nearest',
) → float | None | list_[float] | list_[None]

Get the quantile value of this Series.

Parameters:

quantile

Quantile(s) between 0.0 and 1.0. Can be a single float or a list of floats.

interpolation{‘nearest’, ‘higher’, ‘lower’, ‘midpoint’, ‘linear’, ‘equiprobable’}

Interpolation method.

Returns:

float | None | list[float] | list[None]

A single quantile value if a float is provided, or a list of quantile values if a list is provided.

Examples

>>> s = pl.Series("a", [1, 2, 3])
>>> s.quantile(0.5)
2.0

Return a list of quantiles:

>>> s.quantile([0.25, 0.75], interpolation="linear")
[1.5, 2.5]
