Calculate Average of an Average Measure

[mjholland]

Hi,

I have data for a number of team members showing the start time of visits they made to customers each day for the full year. These team members are divided into a number of teams.

I've been able to use the following DAX measure to find out the average start time for each team members, which can be used across each week of the year:

AvgStartTime = VAR Result = AVERAGEX ( VALUES ( 'TITO Data'[EntryDate] ), CALCULATE ( MIN ( 'TITO Data'[EntryTime]) ) ) RETURN IF ( NOT ( ISBLANK ( Result ) ), Result + TIME ( 0, 0, 0 ) )

This works out the earliest start for each day and takes an average.

This formula works fine when I have a table with each team member in a row but when I try to show what the average start time is across the entire team the results are not correct and I don't know why or how to fix it. Should I be trying to take an average of teh AvgStartTime measure or do I need to do something completely different?

Can anyone help?

You can try to create a summarize table with following formula, then create a simple measure to calculate the team average.

Table = 
SUMMARIZECOLUMNS (
    'TITO Data'[Team],
    'TITO Data'[Team Member],
    'TITO Data'[Customer],
    'TITO Data'[EntryDate],
    "MinEntryTime", MIN ( 'TITO Data'[EntryTime] )
)

AvgStartTime_Team = 
VAR Result =
    AVERAGE ( 'Table'[MinEntryTime] )
RETURN
IF ( NOT ( ISBLANK ( Result ) ), Result + TIME ( 0, 0, 0 ) )

Best Regards,

Herbert

Hi @v-haibl-msft, this looks like it's working.

I've actually now created a summary table in QueryEditor to bring in additional information I'll need to report on by team then used the second measure to get the average I needed.

Thanks for your help,

Can you post some sample data so that we can recreate it, observe the issue and then come up with a fix.
