    See modified Power BI file here.

You need to use the STDEVX.P() function.  Please try this approach 

 

Std Complex = STDEVX.P(VALUES(Table[Seller Name]), CALCULATE(Average(Table[Avg Sales Per Day])))
 
Where Table is your table name and the column (not measure) is in the Average().  Having the Calculate is required (or you can just use your measure that is the average of that column instead).
 

If this works for you, please mark it as solution.  Kudos are appreciated too.  Please let me know if not.

Regards,

Pat

      Can you share a Power BI file with a sample of your data so we can work with this?
