AVERAGE IF function DAX
Hey,
Wonder if there is a way to make a calculated measure to calculate the average of all numbers that belongs to a certain category.
For example, if there is a DAX expression to calculate the average of all numbers belonging to Computers:
7 Computers
7 Cell phones
7 Gaming consoles
6 Computers
5 Cell phones
10 Gaming consoles
11 Computers
5 Cell phones
2 Gaming consoles
Thanks in advance!
If you want to calculate the average only for 1 category at a time go with the above method
However if you have MANY more categories you can create a simple average measure and use it in a Matrix
Place category in the Rows and that Measure will be sliced per Category
Average Measure = AVERAGE ( 'Table'[Value] )
Even easier you can just drag the value column again to the Values area - right click and change the aggregation - as shown below...
Hope this helps! :smileyhappy:

What if you didn't necessarily want to create a matrix, but rather a new column? For example, I'm working with position-level data (granular) but I need to calculate weighted-average (not simple averages) analytics that are grouped by various categories like Industry. So to start, I have a column that shows the weight of each position relative to the dataset as a whole, but I need to find the weight of each position relative to that position's industry.
In excel, I did it like this:
=AVERAGE(IF($B$2:$B$229=$G2, $C$2:$C$229))*0.01
can you please clarify how you'd use the same formula
AverageNumberofComputers=Calculate(average(Table[ColumnNumbers]),Filter(Table, Table[ColumnName]="Computers"))
but instead of filtering by a defined value ("Computers") to filter it by the each single line value of the "[ColumnName]" column?
