values in the `_value` column of each input table.
Output tables contain a single row the with the calculated mean in the `_value` column.
_`experimental.mean()` is an [aggregate function](/flux/v0.x/function-types/#aggregates)._

```js
import "experimental"

experimental.mean()
```

## Parameters

### tables {data-type="stream of tables"}
Input data.
Default is piped-forward data (`<-`).

## Examples
```js
import "experimental"

from(bucket: "example-bucket")
    |> filter(fn: (r) => r._measurement == "example-measurement" and r._field == "example-field")
    |> range(start: -1h)
    |> experimental.mean()
```
