Hi Anonymous 

 

Thanks to lbendlin for the correct direction. If I understand it correctly, you can try a new column with below DAX.

RankGroup = 
VAR vSalesAmt = 'Table'[SalesAmt]
RETURN
SWITCH(TRUE(),
vSalesAmt<PERCENTILEX.INC('Table', 'Table'[SalesAmt], 0.1),1,
vSalesAmt<PERCENTILEX.INC('Table', 'Table'[SalesAmt], 0.2),2,
vSalesAmt<PERCENTILEX.INC('Table', 'Table'[SalesAmt], 0.3),3,
vSalesAmt<PERCENTILEX.INC('Table', 'Table'[SalesAmt], 0.4),4,
vSalesAmt<PERCENTILEX.INC('Table', 'Table'[SalesAmt], 0.5),5,
vSalesAmt<PERCENTILEX.INC('Table', 'Table'[SalesAmt], 0.6),6,
vSalesAmt<PERCENTILEX.INC('Table', 'Table'[SalesAmt], 0.7),7,
vSalesAmt<PERCENTILEX.INC('Table', 'Table'[SalesAmt], 0.8),8,
vSalesAmt<PERCENTILEX.INC('Table', 'Table'[SalesAmt], 0.9),9,
10)

Thank you Anonymous and lbendlin for the reponses. I believe the PERCENTILEX.INC function is the right way to go. Can you explain why you use expressions 0.1, 0.2 ,0.3, etc...? When I apply this formula to my specific case I only get a rank group from 8-10.

    how much data do you have?  Needs to be statistically significant.
