Hello,
For a exercise I need to print out the quartieles of a number of values.
Lets say we have this 1,2,3,4,5,6,7,8,9.
First quartiel can be found at : 9/4 is 2,25
So the first quartiel is between the 1 and 2.
Can I say that the first quartiel can be calculated by 2 + (2-1) * .25
second quartiel can then be found at 9/2 = 4,5
Thirst quartiel can be found at 9 *.75 so it's 6.75 .
Can I say that it's 6+(7-6) * 0.75.
Sorry for asking but maths for me is like 20 years ago.
