How to write a measure to calculate 5th percentile

[Cevola]

Hi,

I want to write a measure to calculate 5th percentile of the VALUE column. I am new to Power BI

Id	Value	%GT Value
A1	2.993857962	2.88%
A2	4.790980789	4.61%
A3	5.285423474	5.08%
A4	9.845946214	9.47%
A5	13.1619472	12.65%
A6	3.061712719	2.94%
A7	14.10853515	13.56%
A8	20.40455305	19.62%
A9	8.082005991	7.77%
A10	0.927973851	0.89%
A11	9.357774268	9.00%
A12	12.00309514	11.54%

Please help

Create a measure and use it in a Card visualization in this format, and let me know if there is any issue.

It works in the Card, But can I get a new column PERCENTILE

Id	Value	%GT Value	Percentile
A1	2.993857962	2.88%
A2	4.790980789	4.61%
A3	5.285423474	5.08%
A4	9.845946214	9.47%
A5	13.1619472	12.65%
A6	3.061712719	2.94%
A7	14.10853515	13.56%
A8	20.40455305	19.62%
A9	8.082005991	7.77%
A10	0.927973851	0.89%

Hi @Cevola ,

According to your description, here are my steps you can follow as a solution.

(1) My test data is the same as yours.

(2) We can create  measures. 

Per = PERCENTILE.INC('Table'[Value],0.05) 

Per_V = CALCULATE([Per],ALL('Table'))

(3) Then the result is as follows.

Hi,

PERCENTILE.INC('YourTableName'[VALUE], 0.05)

Hi, I have written this measure but when I pull this measure in the visualisation I get the values same as in the VALUE column
