Quartiles In DAX

Dustin Ryan shows us how to calculate quartiles using DAX:

To calculate the quartile, we’re going to use the PERCENTILEX.INC DAX function. The PERCENTILEX.INC function returns the number at the specified percentile. So for example, if I had numbers 0 and 100 in my data set, the 25th percentile value would be 25. The 50th percentile value would be 50 and the 75th percentile value would be 75, and you can figure out what the 100th percentile value would be.

Dustin shares an example with his NFL data set and also walks us through a couple of tricky situations.
