# execute(statistic:value:)

Generates output data from the specified statistical value.

## Declaration

```swift
nonisolated(nonsending) func execute(statistic: String, value: Double) async throws -> SearchPipelineData
```

## Parameters

- `statisticName`: The name of the statistic. This parameter contains strings like “average”, “max”, “min”, “sum”, “median”, or “stddev”.
- `value`: The value for the statistic.

## Return Value

Return Value A pipeline data structure with data your stage produced. Make sure the output you return matches the output you specified in the outputType property.

## Discussion

Discussion If your stage supports a statistical value as input, implement this method and use it to generate your stage’s supported output data. Write your code to run in parallel with other instances of your stage and instances of other stages. The best approach is to use only the contents of the items parameter and local intermediate values you create to deliver the output data.
