The problem i am attempting to solve is simple to do in SQL but I would like to derive the DAX equivalent.
I want to count the number of users who do not have a score in the Results Table.
These tables are link via the UID field.
I'm sure the solution is simple but i just can't conceptualize it 😞
Solved! Go to Solution.
A simple measure that should achieve this is:
Count of Users Without Score = COUNTROWS ( EXCEPT ( VALUES ( Users[UID] ), VALUES ( Results[UID] ) ) )
This would respond to any filters on either Users or Results tables.

Thank you @OwenAuger
I needed to also add a filter but the end DAX measure looks like this
Calculate ( CountRows ( Except( Values('Users'[UID]), Values('Results'[UID]))) , 'Results'[Exam] = "English")
So i can count where the User does not have an enlgish score.
Much Appreciated.
