# median
|
|
|
|
The `median*` functions are the aliases for the corresponding `quantile*` functions. They calculate median of a numeric data sample.
|
|
|
|
Functions:
|
|
|
|
- `median` — Alias for [quantile](../../../sql-reference/aggregate-functions/reference/quantile.md#quantile).
|
|
- `medianDeterministic` — Alias for [quantileDeterministic](../../../sql-reference/aggregate-functions/reference/quantiledeterministic.md#quantiledeterministic).
|
|
- `medianExact` — Alias for [quantileExact](../../../sql-reference/aggregate-functions/reference/quantileexact.md#quantileexact).
|
|
- `medianExactWeighted` — Alias for [quantileExactWeighted](../../../sql-reference/aggregate-functions/reference/quantileexactweighted.md#quantileexactweighted).
|
|
- `medianTiming` — Alias for [quantileTiming](../../../sql-reference/aggregate-functions/reference/quantiletiming.md#quantiletiming).
|
|
- `medianTimingWeighted` — Alias for [quantileTimingWeighted](../../../sql-reference/aggregate-functions/reference/quantiletimingweighted.md#quantiletimingweighted).
|
|
- `medianTDigest` — Alias for [quantileTDigest](../../../sql-reference/aggregate-functions/reference/quantiletdigest.md#quantiletdigest).
|
|
- `medianTDigestWeighted` — Alias for [quantileTDigestWeighted](../../../sql-reference/aggregate-functions/reference/quantiletdigestweighted.md#quantiletdigestweighted).
|
|
- `medianBFloat16` — Alias for [quantileBFloat16](../../../sql-reference/aggregate-functions/reference/quantilebfloat16.md#quantilebfloat16).
|
|
- `medianDD` — Alias for [quantileDD](../../../sql-reference/aggregate-functions/reference/quantileddsketch.md#quantileddsketch).

**Example**
|
|
|
|
Input table:
|
|
|
|
``` text
|
|
┌─val─┐
|
|
│ 1 │
|
|
│ 1 │
|
|
│ 2 │
|
|
│ 3 │
|
|
└─────┘
|
|
```
|
|
|
|
Query:
|
|
|
|
``` sql
|
|
SELECT medianDeterministic(val, 1) FROM t;
|
|
```
|
|
|
|
Result:
|
|
|
|
``` text
|
|
┌─medianDeterministic(val, 1)─┐
|
|
│ 1.5 │
|
|
└─────────────────────────────┘
|
|
```
