In math we learned the Box and whiskers plot so you have some numbers like 4,5,8,9,3 and put them in order 3,4,5,8,9 then you have a strait line and you put a dot in the middle where you put your median (your middle number) and a dot on each end for your lowest and highest numbers . Then you put a box around the middle dot and on the lines of the box you put the first and third cortile ( the median of the numbers before and after the midian and if there’s no median the average of the numbers. So it would go on the line 3′ 1.5, 5, 8.5, 9.
