Getting averages from SPECIFIC rows

[steambucky]

Units of a department are getting evaluated on 4 things.  Anywhere there is a 0 means that unit is not yet evaluated. I need to create averages from units that HAVE been evaluated. 

This is the data: 

Department	Unit	Staff Efficency	Staff training	Manager Efficency	Manager Training
Natural resources, Mines and Energy	Mines	3	2	2	4
Natural resources, Mines and Energy	Environmental Science	0	0	0	0
Natural resources, Mines and Energy	Fisheries	0	0	0	0
Natural resources, Mines and Energy	Energy	2	3	4	2
Natural resources, Mines and Energy	Climate science	1	2	1	5

This is the desired output is something like this: 

	Staff Efficency	Staff training	Manager Efficency	Manager Training
Natural resources, Mines and Energy - Average scores	2	2.3	2.3	3.6

Doing the averages with but including the two units that have ZEROs in the data will create averages like this: 

	Staff Efficency	Staff training	Manager Efficency	Manager Training
Natural resources, Mines and Energy - Average scores	1.2	1.4	1.4	2.2

Whats the easiest way can get the averages of the units that HAVE been assessed? 

Note: If change my base data and subsitute "NOT ASSESSED" for the 0s, Excel is happy enough to only calculate averages on the numbers in the columns and gives me the right result. Power BI doesnt like the like a mix of data types ( numbers and text ) and and I get errors.

Hi @steambucky ,
Please try this 

Mgr EfficiencyAverage no zeros = CALCULATE(AVERAGE(NR[Manager Efficency ]),NR[Manager Efficency ]<>0)

Let me know if you have any questions.

If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos are nice too.

Check if this can work for you

calculate(avergae(	Staff Efficency ),	Staff Efficency <>0)

avergae(filter(table,Staff Efficency <>0)Staff Efficency )

You can use AVERAGEX and replace the zeros with blanks in the measure without changing your underlying data. Blanks are not evaluated with the AVERAGEX function.

Manager Training Avg = 
    AVERAGEX('DataTable',
        IF(
            'DataTable'[Manager Training] > 0,
            'DataTable'[Manager Training],
            BLANK()
            )
    )
