Median Measure using Distinct Values

[ace_SB]

Hi All,

I have a dax formula, see below, to calculate Median. It uses the scores for only selected students and ignores nulls. What I need to do is use distinct values for Score1 while calculating the Median. Is that possible? I think we can use Distinct(), but not sure where should I put that in this DAX. Thanks for your assistance.

MedScore = ROUND(
CALCULATE(
   medianx(FILTER(vw_ABC, vw_ABC[Score1]<> BLANK()),

              vw_ABC[Score1]) ,

           TREATAS(VALUES('vw_Option'[StuName]),vw_ABC[IStuName])
),0
)

Hi @ace_SB

Try this

MedScore =
ROUND (
    CALCULATE (
        MEDIANX (
            FILTER ( VALUES ( vw_ABC[Score1] ), vw_ABC[Score1] <> BLANK () ),
            vw_ABC[Score1]
        ),
        TREATAS ( VALUES ( 'vw_Option'[StuName] ), vw_ABC[IStuName] )
    ),
    0
)

Actually this works. Thanks a lot.

Thanks Zubair. Use of Values() is great, but it is still not working. I need to put it in the right place. What I need is median for not null distinct values for only those students picked by the slicer using the view "vw_Option"...
