Computes the specified quantile of all grouped values.
quantile(xs:list, q=float) -> floatDescription
The quantile function returns the quantile of all numeric values in xs,
specified by the argument q, which should be a value between 0 and 1.
xs: list
The values to evaluate.
q: float
The quantile to compute, where q=0.5 represents the median.
Examples
Compute the 0.5 quantile (median) of values
from {x: 1}, {x: 2}, {x: 3}, {x: 4}
summarize median_value=quantile(x, q=0.5)
{median_value: 2.5}
