Dynamic Percentiles

[Anonymous]

Hello community,

I have the below dataset that has grades from students in each department. I want to calculate percentiles (p25, p50, p.75) for all students but also when I filter with slicer the Department I want to see the percentiles for that category only.

ID	Department	Grade
1	A	7
2	A	8
3	A	6
4	A	5
5	A	8
6	A	9
7	A	6
8	B	4
9	B	3
10	B	5
11	B	6
12	C	7
13	C	8
14	C	6
15	C	5
16	D	6
17	D	7
18	D	6
19	D	5
20	D	10

Many thanks!

Hi @Anonymous ,

You can try below formula:

M_0.25 =
CALCULATE (
    PERCENTILE.EXC ( 'Table'[Grade], 0.25 ),
    ALLEXCEPT ( 'Table', 'Table'[Department] )
)

M_0.5 =
CALCULATE (
    PERCENTILE.EXC ( 'Table'[Grade], 0.5 ),
    ALLEXCEPT ( 'Table', 'Table'[Department] )
)

M_0.75 =
CALCULATE (
    PERCENTILE.EXC ( 'Table'[Grade], 0.75 ),
    ALLEXCEPT ( 'Table', 'Table'[Department] )
)

If the problem is still not resolved, please provide detailed error information and let me know immediately. Looking forward to your reply.

Best Regards,
Henry
