Average everything else

Hi stjimi 

From your example, it looks like a measure such as this would give the result you want:

Average of others = 
CALCULATE ( 
    [Average],
    EXCEPT ( 
        ALLSELECTED ( YourTable[Jurisdiction] ),
        VALUES ( YourTable[Jurisdiction] )
    )
)

This assumes a measure [Average] is already defined.

The EXCEPT ( ... ) expression creates a modified filter on Jurisdiction, by taking the filter on Jurisdiction applying to the overall visual, and removing the value(s) of Jurisdiction visible in the current filter context, i.e. removes the single value from the current row of your table in your example.
