Averaging Distinct Counts in a Pivot Table

OK, I've created a Pivot Table that pulls the distinct count of patient identifiers per date in one column by the date in the rows from a query.  I'm trying to get a calculation of the average daily number of distinct patient identifiers but I'm struggling.  I've added the data to the Data Model and tried to play around with measures, but just can't get it to work.  Any ideas?  How do you get Excel to calculate a distinct count for each day and then average those distinct counts by the number of dates in the Pivot Table?  Sorry I can't provide a test sheet with this question.

@Ramiz_AssafWell I thought I responded earlier but it didn't go through.  I added an example sheet to the original post.  I used a pivot table and the data model to get the distinct count by patient ID, but then I want to get the daily average of distinct patient IDs.  I know I can just plug the grand total cells into an average formula but I'd like it to be a little more automated since the data table will just continue to grow.

``````Daily Average of Unique Patients:=AVERAGEX(
SUMMARIZE(
Range,
Range[DATE],
"Daily Unique", DISTINCTCOUNT(Range[Patient ID])
),
[Daily Unique])``````

Result is like

Re: Averaging Distinct Counts in a Pivot Table

Hi, I'm trying to do something similar. I've Purchase Order numbers, split per line. I'm looking to get the average order value per PO. It's easy to get the average value per line, but what I need is the average value per distinct PO number. I've attached an excel as an example, but my dataset is much larger. In the example the average value is 288 for everything but I need to know the average of each PO. The value I need is £396.10 which is the total for each PO number divided by the amount of PO's placed (8 in this example).

 PO Number PO Line Number PO Value GBP Equiv O033314 001 193.5 O033314 002 50.08 O033315 001 13.23 O033315 002 34.79 O033316 001 11.11 O033317 001 95 O033318 001 1465 O033319 001 248.2 O033320 001 100 O033321 001 954.78 O033321 002 3.13
