Average of count distinct values by month

[atpbi10]

I have the following table

Name	Date	Month	Day	SomeValue
John	01/01/2021	1	1	8
John	02/01/2021	1	2	2
John	02/01/2021	1	2	10
Arnold	02/01/2021	1	2	4
Sam	02/01/2021	1	2	99
Sam	02/02/2021	2	2	7

Im trying to figure out a way to count distinct values of a column 'NAME' in a month (so by each day)

Which means that Im trying to calculate how many different people were on average every day in a given month.

So based on that I would get the following result

Month  Daily_Average_of_distinct_names

1            (1+3)/2=2

2            1

I think this is good to create for a measure, am I right? I tried different combinations of AVERAGEX but they are not working at all like for instance:

AVERAGEX(VALUES(Sheet1[Month]), DISTINCTCOUNT(Sheet1[NAME]))

Any ideas how I could solve this problem?

Hi @atpbi10 ,

Try to create measures like below

d_count_name = CALCULATE( DISTINCTCOUNT('Table'[Name]),FILTER('Table','Table'[weekday]<>2))+0

Measure 2 = CALCULATE(AVERAGEX(VALUES('Table'[Month]),[d_count_name]),REMOVEFILTERS('Table'[weekday]))

This worked for me:

AVERAGEX(VALUES(Sheet1[Date]),calculate( DISTINCTCOUNT(Sheet1[NAME])))

But I cant figure out how to filter out "Sunday" and "Saturday" from the column day_of_the_week

Hi @atpbi10 ,

The formula I created is to filter day_of_the_week, which is tested to be valid in my sample data.

If the problem persists,could you share the sample pbix via cloud service like onedrive for business?

@atpbi10 , Try

AVERAGEX(summarize(Table, Table[month], Table[Day],"_1", DISTINCTCOUNT(Sheet1[NAME])),[_1])

or
AVERAGEX(VALUES(Sheet1[Date]),calculate( DISTINCTCOUNT(Sheet1[NAME])))

Seems to be working for me (the second one). Is it possible to add some filter to the AVERAGEX? Like I want to calculte the above, but exclude some observations based on value in another column- lets say DayOfWeek.

So filter out DayOfWeek != Saturday/ Sunday
