Calculate average value per weekday

[icturion]

Hi

The aim is to calculate the average value per day of the week.

Table:

I only get the average per record and not the average per day of the week. 

Maybe someone can help

@icturion , have date table, There you define a week and week rank as column

Week Rank = RANKX(all('Date'),'Date'[Week Start date],,ASC,Dense)

And use a measure like this
This Week = CALCULATE(AverageX(values(Date[Date]),Sum(Table[Antal monsters])), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])))

I'm probably doing something wrong, because the results are wrong. Suppose on Sundays in September I took a total of 20 samples. so far September has had 2 Sundays. then the average should be 10 samples per Sunday.

Hi,

I revolved it:

Measure 1  = SUM(Table [aantal monsters])

measure 2 = AverageX ( VALUES(table[DATE]), [measure 1])

thx
