Hi! Inside of my program I need to find the 1st and 3rd quartiles of a list. Unfortunately their is no function that returns this (just 1-varstat, however I can not access the results of that programatically… right).
What would be the fastest method to find the index of Q1, and Q3 in a list of numbers. I know you can easily find Q2 by doing (length + 1)/2, however I cant find anything for the other quartiles.
