Calculate standard deviation and Zscore

Hi all,

 I want to calculate Zscore for each progarm manager by using his score according to his delivery managers project count.Suppose x is the pro.manager and his score is 10 and his delivery manager having projects count 24, then by using score and project count I need to calculate Zscore and for that first need to calculate mean and Standard deviation.DM.PNG

above table is DM table where I have DM and his project count. 

PM.PNG

and this table showing pro.manager and his data where I have score and DM name. I have another table i.e PM Name table where I listed only PM names. I set relationship in DM table and PM table using this table.

 

I have calculated mean using DAX by following formula :

mean= Score / No.of projects

 

Now I need to calculate Standard deviation and Zscore using above data. Please help me.

Re: Calculate standard deviation and Zscore

Hi @supriyad,

 

DAX provides function STDEV.P to return the standard deviation of the entire population.

 

Here are two examples about Standard deviation and Zscore calculation for your reference.

Can PowerBi give me Z-Scores

Standard Deviation and Z-Score calculation depending on time slicer
