Calculating average daily count from counting rows?

[leobelyaev]

Hello,

New user.

I am not sure how to approach the project, since I am usnsure how to 'nest' functions in Power BI DAX or if that's even necessary.

Here's what My Dataset looks like:

Each row represents an encounter.

My final result should be a dashboard that displays the average number of visits by DayOfWeek  (Monday, Tuesday etc.)

Ideally it needs to be able to show data at different levels. Either using drill through, toggle, slicer or have different tables showing:

Avg. number of visits by

Provider(VISIT_PROV_NAME),

Encounter Type(ENC_TYPE_TITLE),

Facility (FAC_ID)

modality (prc_modality).

I am not sure how to tackle this assignment in Power BI, but here are some steps I took to query for the same data in SQL, wonder if any of that logic carries over or helps at all.

1.Counted and summed up number of encounters by APPT_Date (by date), to get Daily Encounters

2. Got the average for Daily Encounters

3.Filtered by DayOfWeek, Provider, Enounter type, Facility, Modality.

I am now wondering if it is possible, and how hard it would be to perform the same process in Power BI, though I am very new.

Any help on how to approach this would be greatly appreciated!

Any suggestions on good tutorials etc. would be appreciated too!

Thanks!

@leobelyaev , Avg Daily would be like

Averagex(Values(Date[Date]), calculate(Count(Table[Column])) )

If you want to switch with the level you can use isinscope

Hi, thank you so much Amit Chandak,

That helped a lot, I checked out your tutorial and used the code you sent.

However, I get very different results when using the formula you suggested, and when i tried to copy the forumla from your tutorial. I can't quite figure out why and how the results are so different from using seemingly similar logic behind the two formulas.

Do you think you could explain how this could be happening? If you could, you'd be better than ChatGPT, because it failed to explain to me hahah.

The first matrix uses this measure: 

Average visit = AVERAGEX(SUMMARIZE(PRC,PRC[APPT_DATE].[Date]),COUNT(PRC[ENC_TYPE_TITLE]))

The second uses this measure:

avg = AVERAGEX(Values(PRC[APPT_DATE]),CALCULATE(COUNT(PRC[ENC_TYPE_TITLE])))

By the way, planning to watch the rest of your 11.5 hour beginner course, you are great at explaining concepts, hands on, with examples, step by step! I really liked what I saw so far!
