    Hi Anonymous 

     

    Here is the DAX statement you can use

     

    AvgSampleNumber =
CALCULATE (
    AVERAGE ( DataSetTabl[Value] ),
    ALLEXCEPT ( DataSetTabl, DataSetTabl[Sample number] )
)

    Does that work for you?

    That worked!!  Thank you for your help. 

    I have another issue now. Sometimes the Value can be blank and if so, the formula ignores that e.g.

     

    1010101,  13

    1010101,

    1010101, 85 

    1010101,

    1010101, 31 

     

    The formula is returning 43 but i would like it to return 25.8

      Hi,

       

      i think you either edit your database in the query when blank=0, then the averagex() should work.

      OR

      you can count of sample number to avoid the values being blank.

      In Power Query use the Replace Value function

    Thank you all for your replies. 

     

    This did do the trick for me Geradav 

    AvgSampleNumber =
CALCULATE (
    AVERAGE ( DataSetTabl[Value] ),
    ALLEXCEPT ( DataSetTabl, DataSetTabl[Sample number] )
)

     

    I have another issue now where i would like to calculate the average between two dates e.g. 

    Currently its calculating the average over all sample numbers while ignoring the sample date. 

    I would like to calculate and display the average between

    2016-17

    2017-18

    2018-19

     

    If sample number date is 01/05/18, i would like the average column to display the average by calculating over all samples from 2018 only. 

     

    Any help would be appreciated!

      Maybe you'll need to open a separate post for that.

      And providing some sample data might help too
