I wish to apply PERCENTILE.INC on the following 'Table2' where [Number_Of_Customers] is aggregated on [Brand] and [Year] level
City
Number_Of_Customers
Birmingham
...
Bristol
...
London
...
Manchester
....
York
....
where in 'Table2' I filter columns [Brand] and [Year] with multi-valued filters,
e.g. for [Brand] = "A" and [Year] = {"2019","2020"} the 75th percentile should be 2917 (I get this result from EXCEL function PERCENTILE.INC).
So far used the following formula
75th_Percentile =
CALCULATE(
PERCENTILE.INC(Table1[Number_of_Customers],0.75),
ALL('Table1'[City])
)
but this doesn't work ( see image below where I get wrong value [75th_Percentile] = 2240,25 ).
Any ideas how to solve this?

Answer 1

Second try:
75th_Percentile =
VAR a = CALCULATETABLE(ADDCOLUMNS( SUMMARIZE( Table1 , Table1[City]), "#total", CALCULATE(SUM(Table1[Number_of_Customers]))), ALLSELECTED(Table1))
RETURN PERCENTILEX.INC (a, [#total],0.75)
First try:
What happens if you remove the calculate?
75th_Percentile =
PERCENTILE.INC(Table1[Number_of_Customers],0.75)
