Wrong calculation of the medianX

Hello everyone, here I am counting weighted averages based on member data. The problem is that if I have empty values then my function takes into account these members and therefore calculations are not correct.

//
MEDIANX
(SUMMARIZE('2021','2021'[SMI_CODE],"Comp1 AVG",
CALCULATE(AVERAGE('2021'[COMP3TGT]),'2021'[COMP3TGT]>0)),[Comp1 AVG])
//

As you can see on my code I've applied to count only for member where value is >0.

HI @konwes97,

Perhaps you can try to add this filter on your parameter table to exclude these not match records before calculations:

formula =
MEDIANX (
    SUMMARIZE (
        FILTER ( '2021' , '2021'[COMP3TGT] > 0 ),
        '2021'[SMI_CODE],
        "Comp1 AVG", AVERAGE ( '2021'[COMP3TGT] )
    ),
    [Comp1 AVG]
)

If the above formula does not help, please share more detailed information to help us clarify your scenario to test.

Hello,

 

I am using the formula above, however, some of the values are being ignored and therefore the medianx returns the wrong value. 

I have a 3 tables that is filtered by the user via a slicer. They are copies of the same source, I am using SUMX, AVERAGEX and MEDIANX respectively, all works fine in the first two, only MEDIANX is ignoring some, sometimes all values, depending on the slicer selection.

 

Here is the formula:

    MEDIANX(
        SUMMARIZE(                                          
            'fct_table',
            'fct_table'[Column_1],        
            'fct_table'[Column_2],                  //primary key for this column is in the slicer, relationship is fine
            "Correct Total",[my_measure]      //my measure is a sum with a filter on the date table
            ),
            [Correct Total]                                 
    )
 
Where am I going wrong? Why does this work for SUMX and AVERAGEX and not for MEDIANX?
 
Can somebody help me fix this please?
Thanks a lot, it is driving me mad...

@konwes97 , Check for non blank too

MEDIANX(SUMMARIZE('2021','2021'[SMI_CODE],"Comp1 AVG",
CALCULATE(AVERAGE('2021'[COMP3TGT]),'2021'[COMP3TGT]>0 && not(isblank([COMP3TGT])))),[Comp1 AVG])
