Calculate Average In Pivot Table

[Sloppyjo3]

Hello,

I have a data set that shows the number of items produced and the date they are produced. In a pivot table, I was able to do a total count per day, but what I really want is the average produced per day. Changing the field settings from "count" to "average" doesn't work...how would I get the average produced per day?

Monday	1112​
Tuesday	2157​
Wednesday	1336​
Thursday	1929​
Friday	1660​
Saturday	6​
Grand Total	8200​

If you are currently using a count, it doesn't seem that you have anything to actually average (since a count is basically just counting 1 per row).

Right. So what I want to calculate is the average produced per day of the week. The data set is for a full year.

OK. You're going to need Power Pivot (or Power Query) then because you'll need to create a summary of the count for each day of the year and then average those for each day of the week. (a bit like a pivot based off a pivot)

To elaborate a bit, assuming you have a table called Table1 with a field called Date, you could add a measure called Counter that is just:

=COUNTROWS([Table1])

which will give you a simple count. You can then create a measure called DailyAverage using a formula like:

=AVERAGEX(SUMMARIZE(Table1,[Date],"RowCount",Table1[Counter]),[RowCount])

which essentially does what I described earlier: creates a summary table with the counts for each date, then takes the average of those. If you then have the days of the week in the row area, that measure will give you the average for each date that was a Monday, Tuesday and so on.
