Average measure

[juliaellershaw]

Hi, I have some survey data and am trying to work out the formula for a measure that will give me the average of the answers for only one of the questions. For example, with this example data, how would I get the average just for the answers for Q1?

Question	Answer
Q1	7
Q1	5
Q1	6
Q2	6
Q2	4
Q2	2
Q2	7
Q3	5
Q3	3

Hi  @juliaellershaw ,

There are two ways to do this：

一.

1. Create calculated table.

Q1_avg_column =
CALCULATE(AVERAGE('Table'[amount]),FILTER('Table','Table'[quarter]="Q1"))

2. Result.

二.

1. Create measure.

Q1_avg_measure =
CALCULATE(AVERAGE('Table'[amount]),FILTER('Table','Table'[quarter]=MAX('Table'[quarter])))

2. Place the quarter field in slice, and set Q1_ avg_ Put measure in card

3. Result.

You can downloaded PBIX file from here.

@juliaellershaw , Try like

averageX(filter(Table, Table[Question]="Q1"), Table[Answer])

[juliaellershaw]

That worked, thank you!

Hi,

To your visual, drag Question to the visual and select Q1.  Write this measure

=average(data[answer])

Hope this helps.

Thanks for the formula. I'm getting an error with this seciton "SUMMARIZE('Table','Table'[Q1]," that says it can't find the column for Q1

You need to replace "Table" with the actual name of your table. 

Alternatively, you could just make a table visual on your report page, and add the Question column and the Answer column.  On the Answer column in the field pane, change the aggregation to average.

Measure= var x=SUMMARIZE('Table','Table'[Q1],"av",AVERAGE('Table'[7]))return AVERAGEX(x,[av])
