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.
• medianDeterministic — Alias for quantileDeterministic.
• medianExact — Alias for quantileExact.
• medianExactWeighted — Alias for quantileExactWeighted.
• medianTiming — Alias for quantileTiming.
• medianTimingWeighted — Alias for quantileTimingWeighted.
• medianTDigest — Alias for quantileTDigest.
• medianTDigestWeighted — Alias for quantileTDigestWeighted.

Example

Input table:

┌─val─┐
│   1 │
│   1 │
│   2 │
│   3 │
└─────┘

Query:

SELECT medianDeterministic(val, 1) FROM t

Result:

┌─medianDeterministic(val, 1)─┐
│                         1.5 │
└─────────────────────────────┘
