I am completely new to DAX, and PowerBI, and this must be very easy to do, but I must be missing some basic knowledge.
I have a Table in following format
SomeData MoreData Day1Count Day2Count Day3Count.....
I would like to add a new column that for each Device calculates the Median value for Day1Count, Day2Count, Day3Count... values. What Can I pass as argument to MedianX?
