Calculating Average of sum of time

[JohanBroersma]

Hello,

I have created a measure that shows the time difference between two columns. I have then a sum of these times.

At the top of the report I have a DAX calculation to calculate the average time difference (in this case the response time). The card shows an average of 02:29 (2 hours 29 minutes). If I do a manual calculation I get an average of around 33 minutes (((14 * 60) + 😎 / 25).

DAX calculation for card: 

AverageResponseTime = FORMAT(Calculate(AVERAGEx(incidents,Incidents[creationDate] - Incidents[responseDate])), "HH:mm")

Time difference measure:

Time Difference = SUMX(Incidents, Incidents[creationDate] - Incidents[responseDate])

What I am looking for is the average response time for all incidents.

I might just create a calculated column for the Time Difference, then use that column in the card and change the calculation type of the card to Average.

Pardon my ignorance - I do not know how to change the calculation type of the card.

Could you clarify?

No worries.  If you are using a column value or a calculated column you can add that to fileds then select average from the dropdown.  I don't believe you can do this with a measure however.
