- Re quartiles -
-
- There is an argument for finding the first quartile at position n/4+1/2,
- the median at n/2+1/2 (the usual position) and the third quartile at
- position 3n/4+1/2 in my paper:
- The principle underlying quartiles - a guide for the teacher. Maths. in
- School, Nov. 1991, 20, 5, 30-32.
-
- The generalisation to other quantiles is obvious.
