|
The `median*` functions are the aliases for the corresponding `quantile*` functions. They calculate median of a numeric data sample.

||
|
|
|
||
|
|
Functions:
|
||
|
|
|
||
|
|
- `median` — Alias for [quantile](#quantile).
|
||
|
|
- `medianDeterministic` — Alias for [quantileDeterministic](#quantiledeterministic).
|
||
|
|
- `medianExact` — Alias for [quantileExact](#quantileexact).
|
||
|
|
- `medianExactWeighted` — Alias for [quantileExactWeighted](#quantileexactweighted).
|
||
|
|
- `medianTiming` — Alias for [quantileTiming](#quantiletiming).
|
||
|
|
- `medianTimingWeighted` — Alias for [quantileTimingWeighted](#quantiletimingweighted).
|
||
|
|
- `medianTDigest` — Alias for [quantileTDigest](#quantiletdigest).
|
||
|
|
- `medianTDigestWeighted` — Alias for [quantileTDigestWeighted](#quantiletdigestweighted).

**Example**
|
||
|
|
|
||
|
|
Input table:

|
||
|
|
SELECT medianDeterministic(val, 1) FROM t
|
||
|
|
```
|
||
|
|
|
||
|
|
Result:
