How do you calculate the rolling average per week/month?

[mdbuzzer]

I have bins created from my date field which gets the daily group. 

Is there a way to calculate the weekly average, so for example from April 1st to April 7th it should have an average of 16.2 (excludes cells containing 0).

So for an output I am looking for it to show Week Commencing April 1st then display the average of 16.2, then Week Commencing April 8th to display 27, and so forth.

Thanks in advance

Hi @mdbuzzer ,

1.Create three calculated columns.

weeknum = WEEKNUM([Date],2)

Average = CALCULATE(AVERAGE('Table'[Value]),ALLEXCEPT('Table','Table'[weeknum]))

week = WEEKDAY([Date],2)

2.Create a new table and create a relationship with main table.

Table 2 = FILTER('Table',[week]=3)

 

3.Create a calculated column in the new table.

Rolling average = CALCULATE(SUM('Table 2'[Average]),FILTER(ALL('Table 2'),[Date]<=EARLIER('Table 2'[Date])))

4.The result is as follows.

You can check more details from here.

Perfect! Thank you, that's exactly what I was looking for

@mdbuzzer  ,

a measure like

AverageX(filter(Table, Table[Col]>0),Table[Col])

For week wise data you can have columns like 

Week Start date = 'Date'[Date]+-1*WEEKDAY('Date'[Date],2)+1
Week End date = 'Date'[Date]+ 7-1*WEEKDAY('Date'[Date],2)
Week Rank = RANKX(all('Date'),'Date'[Week Start date],,ASC,Dense)

Measures
This Week = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])))
Last Week = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])-1))
Last year Week= CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=(max('Date'[Week Rank]) -52)))
Last 8 weeks = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]>=max('Date'[Week Rank])-8 && 'Date'[Week Rank]<=max('Date'[Week Rank])))

last two weeks = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]<=max('Date'[Week Rank])-1

not sure i'm getting the right result.

Below are the figures for Week 14 so the average of these values should equal 25.2

But it's returning an average of 3 for Week 14
