The value that is greater than half of all values and less than half of
|
|
all values, also known as the 50% <<esql-agg-percentile>>.

NOTE: Like <<esql-agg-percentile>>, `MEDIAN` is <<esql-agg-percentile-approximate,usually approximate>>.

[WARNING]

====
|
|
`MEDIAN` is also {wikipedia}/Nondeterministic_algorithm[non-deterministic].
|
|
This means you can get slightly different results using the same data.
