Calculate The mean and std based on tow columns from different tables

[ALEX2011ALfer_]

Hi EVERYONE 

I have many tables, what i want is calculate the avg and std for the [Value] 

based on company and State. 

i want to see the avg for all company based on the State. 

let assume that texas state has three company and the [value] fro each company in Texsas are 22,33,55

the avg should be 36.66

same for the std. 

i want to disply my visual as Matrix 

where the row is Cagtory and the Column is the State

and the value is for avg. 

and another matrix for std.

here is the power bi file to unnderstand what I'm saying.  Thanks

Hi @ALEX2011ALfer_ ,

I updated your sample pbix file(see attachment), please check whether that is what you want. You can create the measures as below to get it:

Measure = 
VAR _selcat =
    SELECTEDVALUE ( 'Dimcagtory'[cagtory id ] )
VAR _selstate =
    SELECTEDVALUE ( Dimstate[state id] )
VAR _citylist =
    CALCULATETABLE (
        VALUES ( 'Dimstate'[cityid] ),
        FILTER ( 'Dimstate', 'Dimstate'[state id] = _selstate )
    )
VAR _cmplist =
    CALCULATETABLE (
        VALUES ( 'Dim Company'[company id] ),
        FILTER ( 'Dim Company', 'Dim Company'[cityid] IN _citylist )
    )
VAR _count =
    CALCULATE (
        DISTINCTCOUNT ( 'Fact Product'[Company Id] ),
        FILTER (
            'Fact Product',
            'Fact Product'[Cagtory id] = _selcat
                && 'Fact Product'[Company Id] IN _cmplist
        )
    )
RETURN
    DIVIDE ( [Value], _count, 0 )

Avg = 
SUMX (
    VALUES ( 'Dimstate'[State name] ),
    SUMX ( VALUES ( 'Dimcagtory'[cagtroy name] ), [Measure] )
)

By the way, does the std you mentioned refer to standard deviation? If so, you can refer to the link below to implement it.
