calculate measure as an individual deviance from average

Hi all,

 

I am trying to calculate new measure as a deviation of individual ratio from the overall average ratio across all individuals. It will be displayed in a bar chart and the number of rows will depend on some other attribute slicers so it needs to be a measure so that it can change dynamically.

 

Example data:

 

Person | home_p
xxx       | 1
xxx       | 0
xxx       | 1
xxx       | 0
xxx       | 1
yyy       | 1
yyy       | 1
yyy       | 1
yyy       | 1
yyy       | 1
aaa       | 1
aaa       | 1
aaa       | 1
bbb       | 0
bbb       | 0
bbb       | 0


 

 

The first part is simple

 

home_p_rate = SUM('score'[home_p])/COUNT('score'[home_p])

 

which gives me the individual ratios in the bar chart.

 

Now I need to add something like this to get the deviance from overall average:

 

home_p_rate_dev = SUM('score'[home_p])/COUNT('score'[home_p]) - AverageAcrossAllIndividuals( SUM('score'[home_p])/COUNT('score'[home_p]) )

 

Any idea how to approach this?

 

Thanks

In this scenario, you can use below measure formula to get the deviance from overall average.

 

home_p_rate_dev = 
VAR AverageAcrossAllIndividuals =
    CALCULATE ( AVERAGE ( score[home_p] ), ALL ( score ) )
RETURN
( [home_p_rate] - AverageAcrossAllIndividuals )
