Help with Average formula with filtering

[aashton]

Hello,

I have the fields, Surgeon, Date, Start Time, End Time, Facility, OR.....I would like to find a surgeons average start and end times, overall, but then also be able to find it by Day of Week, Facility, OR, if adding these fields to the visual.  I have the formula:

Anes Start Average = CALCULATE(AVERAGE('Case Details'[Anes Start]), ALLEXCEPT('Case Details','Case Details'[Surgeon]))

Which works if I just display a table with the Surgeon name, and their averages.  If I add additional fields like Day of Week, or Facility, these averages do not change. So I altered the formula to something like:

Anes Start Average = CALCULATE(AVERAGE('Case Details'[Anes Start]), ALLEXCEPT('Case Details','Case Details'[Surgeon],'Case Details'[Facility],'Case Details'[OR]))

Which doesn't work if I just want to display each surgeon and their average start and end times (there are multiple rows if they are linked to multiple facilities, etc)....Don't know how to fix it.

Without knowing the data model, data samples, and what is the output expected, it is tough to advice. For me, it sounds like you are doing average by group and your formula is correct in my view:

Anes Start Average = 

       CALCULATE(

           AVERAGE('Case Details'[Anes Start]), 

           ALLEXCEPT('Case Details',

                  'Case Details'[Surgeon],'Case Details'[Facility],'Case Details'[OR])

         )

Quick check tip: add and delete this table to verify

Assuming you have in the data model, a relation between Calendar Table and Case Details.

1. Click "New Table" in the modeling and add table via DAX

2. Dax formula

New Table = SUMMARIZE( 'Case Details'
                  , 'Case Details'[Surgeon]
                  , 'Case Details'[Facility]
                  , 'Case Details'[OR]
                  , 'Calendar Table'[Month & Year]
                  , "Rows Count 1", Count('Case Details'[Anes Start])
                  , "Avg. Test 1", AVERAGEX('Case Details', 'Case Details'[Anes Start]))
                  , "Avg. Test 2", AVERAGE('Case Details'[Anes Start])
)
