Thanks

A dynamic version of it can be achieved by tweaking Angelia's first version a bit:
Instead of creating Rank in a column, create a measure like this:
Rank := RANKX (ALLEXCEPT ( Table4, Table4[codigo] ), [SumColumn],, 0, SKIP)
with
SumColumn := SUM ( Table4[column] )
in the "number"measure, some important changes are made:
number := CALCULATE ( COUNT ( Table4[column] ), ALLEXCEPT ( Table4, Table4[codigo] ) )
this will count all items per codigo
The final measure will look like this then
TM40% :=
CALCULATE (
AVERAGE ( Table4[column] ),
FILTER (
ALLEXCEPT ( Table4, Table4[codigo] ),
AND (
[Rank]
> INT ( [number] * 0.4 * 0.5 ),
[Rank]
<= (
[number]
 INT ( [number] * 0.4 * 0.5 )
)
)
)
)

Hi Carlos,
I reproduce your scenario in Power Pivot excel 2010 and get expected result.
This is my sample data you can copy it here. Create a linked table, add the sample table into pivot model.
First, you should add a rank column used to rank all the value.
=RANKX(Table4,Table4[column])
Then create measure, I list the percent 20% and percent 40% as example, please review the following screenshot.number:=CALCULATE(COUNT(Table4[column]),ALL(Table4)) 20%:=CALCULATE(AVERAGE(Table4[column]),FILTER(Table4,AND(Table4[Rank]>INT(Table4[number]*0.2*0.5),Table4[Rank]<=(Table4[number]INT(Table4[number]*0.2*0.5))))) 40%:=CALCULATE(AVERAGE(Table4[column]),FILTER(Table4,AND(Table4[Rank]>INT(Table4[number]*0.4*0.5),Table4[Rank]<=(Table4[number]INT(Table4[number]*0.4*0.5)))))
Compare the result in Power Pivot with excel, it's correct.

Angelia

Hi Carlos 2017,
According to your screenshot, you create a calculated column, right? TRIMMEAN in Excel is to calculate one result(trimmed mean) based on a supplied set of values. Measures are used in some of the most common data analysis based on function. So you should create a measure rather than calculated column like posted in this thread.

Thanks for the answer, but the result is not correct

Hi Carlos 2017,
The result is not correct, because your sample data is different from mine. My solution is to calculate the trimmed mean of all values in column. While in your sample data, when you select "a", it will return the trimmed mean of all "a" values? Correspondingly, it will return will return the trimmed mean of all "b" values when you click b?
If it is, you should create two seperate measures.
Rank = RANKX(FILTER(Table4,Table4[codigo]=EARLIER(Table4[codigo])),Table4[column],,ASC,Dense) number_a:=CALCULATE(COUNT(Table4[column]),Filter(ALL(Table4),Table4[codigo]="a")) 40%_a:=CALCULATE(AVERAGE(Table4[column]),FILTER(Table4,AND(Table4[Rank]>INT(Table4[number_a]*0.4*0.5),Table4[Rank]<=(Table4[number_a]INT(Table4[number_a]*0.4*0.5))))) number_b:=CALCULATE(COUNT(Table4[column]),Filter(ALL(Table4),Table4[codigo]="b")) 40%_b:=CALCULATE(AVERAGE(Table4[column]),FILTER(Table4,AND(Table4[Rank]>INT(Table4[number_b]*0.4*0.5),Table4[Rank]<=(Table4[number_b]INT(Table4[number_b]*0.4*0.5)))))
When you select a, you should return 40%_a, and return 40%_b when you click b. Just lick calculate trimmed mean in Excel, it will return different result when you select different scope values.

My real table has many codes in number format (CODE OUVRAGE).
Table Powerpivot
The graph (calcul column (PRIX UNITE REEL))
Thanks

Hi Carlos,
it is not clear to me what your last post meant: Is your problem solved? Then please mark the post that helped it as answer.
If it still doesn't work, please specify.

Hi,
My problem is not solved.
number_a:=CALCULATE(COUNT(Table4[column]),Filter(ALL(Table4),Table4[codigo]="a"))
I have many codes in number format (CODE OUVRAGE). I need calculate TRIMMEAN for each code, there are 900 codes approximately. My really table date is the picture.
Thanks!!!!!
