## Median value not same as Excel

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.
