Need help getting an average of a calculated column

[Anonymous]

I am trying to get an average of the Duration column. Basic format is DD:HH:MM:SS.

Hello

the duration data type does not accept to be summarized, any suggestion to get an average duration to use in a bar chart ?

Thank you

Hi @Anonymous 

As tested, in my excel, the "duration" column is of time type or text type,

after importing to Power BI, i can go to Edit queries to transform it to duration type.

Then in Edit queries->Add columns->Duration->total seconds

Close&&apply, go to report view

Create measures

average = CALCULATE(AVERAGE(Sheet1[Total Seconds]),ALL(Sheet1))

total hours = INT(ROUNDDOWN([average]/3600,0))

Minutes = INT(ROUNDDOWN(([average]-[total hours]*3600)/60,0))

seconds = INT(ROUNDUP([average]-[total hours]*3600-[Minutes]*60,0))

days = INT(ROUNDDOWN([total hours]/24,0))

average format = [days]&"."&([total hours]-[days]*24)&":"&[Minutes]&":"&[seconds]

Best Regards

What if you tried this measure:

Avg Duration = FORMAT(AVERAGE( Duration[Duration] ),"dd:hh:mm:ss")

Not sure how your data is set up, so that's more of a guess

Thanks, Nick. I've tried your suggestion and set up a new measure, but I still get the error : "MdxScript(Model) (4, 57) calculation error in measure 'Export Worksheet'[Avg Duration]: The function AVERAGE cannot work with values of type String.

You can try changing the data type in power query to type Duration. 

if the column errors out when you make that change (not sure where that column comes from) you will then have to calculate the duration yourself using whatever start and end points you want.
