Can anyone help me with developing quartile metrics, 1st, and 3rd. Tableau has the standard min, median and max but I need the 1st and 3rd quartiles to finish a project. Thanks for the help.
I posted this approach for quantiles in general a while back - so you just need to use 0.25, 0.5 and 0.75 for quartiles. It's a bit tricky to set it up, but it works well.
