Hello.

I see **4 settings** related to _standard deviation_ in timeseries builder.

![image](https://us1.discourse-cdn.com/elastic/original/3X/0/8/0828b67f67a581f67509112b8c81ae567b7f1d2b.png)

Extended aggregation also returns **4 results**. _Variance_ , _std\_deviation_, _std\_deviation\_bounds (upper and lower)_

```auto
GET validation_result/_search
{
  "size": 0,
  "aggs": {
    "stats": {
      "extended_stats": {
        "field": "validation.amount",
        "sigma": "0"
      }
    }
  }
}

RESULT:

  "aggregations" : {
    "stats" : {
      "count" : 152,
      "min" : 0.0,
      "max" : 16.0,
      "avg" : 2.0789473684210527,
      "sum" : 316.0,
      "sum_of_squares" : 2516.0,
      "variance" : 12.23060941828255,
      "std_deviation" : 3.4972288198347203,
      "std_deviation_bounds" : {
        "upper" : 2.0789473684210527,
        "lower" : 2.0789473684210527
      }
    }

```

However,some of the terminology in kibana does not match from aggregation result.

Is below understanding correct ?

1. Raw = std\_deviation
2. Bounds Band = variance

Thanks,  
Yu Watanabe

`Bounds Band` displays both `Upper bound` and `Lower bound`.
