I am pretty new to power bi.
So I am trying to calculate median and have been getting difference in values when I calculate edian using excel and when I use power bi to do the same.
An example of my table is as follows:
Class | marks | Roll No |
A | 12 | 1 |
A | 45 | 14 |
B | 12 | 13 |
D | 45 | 17 |
C | 24 | 69 |
B | 26 | 40 |
B | 12 | 17 |
C | 15 | 13 |
D | 67 | 66 |
Now I plan at getting median by class. My formula works however there is a difference i result when I compare the same with median from excel.(again i am not talking about the total median but individual medians by class). this diffrence is only when the number of data points(in thiscase count of marks in a class) is odd. Somehow power bi take the average of thee middle and middle +1 value.

Hi @Anonymous ,
I test this in my emviornment, I get result like below
Measure = CALCULATE(MEDIAN('Table'[marks]))
The results are the same, and you could refer to https://www.mathsisfun.com/median.html for logic.

Hi @Anonymous ,
I have shown DAX in above post , you could refer to it, and below is expression to calculate median in excel
If you have other fields, you also could add it in below expression
CALCULATE(MEDIAN('Table'[marks]), ALLEXCEPT('Table','Table'[Class]))

Could you share the dax used. I do the logic behind getting the medain ut having problems on what result my dax throws me.
