# Avg Sales Per Week Day using DAX

Hi, all. I have a dimension table that is a standard date dimension table - has all the usual elements (date, day of week, week number, month number, etc).

I also have a fact table with sales for each date.

I am interested in getting the average sales per day of the week. For example, average sold on Monday. Average sold on Tuesday. Etc.

I am using: AVERAGEX(VALUES(dCalendar[Day of Week]),[QTY]) but it's producing numbers that don't square with reality.

Any other suggestions?

It's not clear how you'd like to use it. If the model is like

``Average Qty:=AVERAGE( Table1[QTY] )``

and show it as

# Re: Avg Sales Per Week Day using DAX

@Sergei, Thank you. This is giving me the average of each order on those week days. I am looking for the average of the total quantity for each of those weekdays. That's why I tried AVERAGEX because it would sum the quantity for each weekday first, then run the average for each weekday.

If I understood your logic correctly that could be

``````Total Qty:=SUM( Table1[QTY] )
Another Average:=AVERAGEX( 'Calendar', Table1[Total Qty] )``````

Another way is

``````Distinct Dates:=DISTINCTCOUNT( Table1[Date] )
Same Average:=DIVIDE( [Total Qty], [Distinct Dates], 0 )``````
