Averages Showing Wildly Incorrect Numbers

Hi  Anonymous ,

I created some data:

I'm not very clear about what you mean by date average, whether it refers to the average of the minimum date and the maximum date (hh:mm:ss), if it's convenient, you can explain the logic of date average, we can help you better.

Here are the steps you can follow：

1. Create calculated column.

If you want to get the average of the minimum and maximum dates after grouping (hh:mm:ss)

AVG(hhmmss) =
var _mindate=
MINX(FILTER(ALL('Table'),'Table'[Group]=EARLIER('Table'[Group])),[Scheduled DropOff])
var _maxdate=
MAXX(FILTER(ALL('Table'),'Table'[Group]=EARLIER('Table'[Group])),[Scheduled DropOff])
var _second=
DATEDIFF(
    _mindate,_maxdate,SECOND)
var _count=
COUNTX(
  FILTER(ALL('Table'),'Table'[Group]=EARLIER('Table'[Group])),[Scheduled DropOff])
var _avg=
DIVIDE(
    _second,_count)
RETURN
TIME ( 0, 0, FLOOR ( _avg, 1 ) )

If you want to get the average date between the minimum and maximum dates after grouping.

AVG =
var _mindate=
MINX(FILTER(ALL('Table'),'Table'[Group]=EARLIER('Table'[Group])),[Scheduled DropOff])
RETURN
_mindate + [AVG(hhmmss)]

2. Set the data format as follows.

3. Result:
