RE: stat: Quartile methods
Hello,

Some mathematics definition are 'culture dependent'.
For example a triangle is defined in Latin country as polygon formed of 3 points. In Anglo Saxon countries as a polygon formed by 3 non-aligned points. It makes a difference.

It is the same for Quartiles.
To find quartiles, you have to first find the middle of an ordered list.
BUT how do you defined the middle of an odd sized list? multiple answers, multiple systems.
Then, you have to find the middle of the 2 sides. Well, what do you do with the middle that you already found? Do you include it in the sides or not? multiple answers, multiple definitions of Quartiles...

At this point, Prime supports the Anglo Saxon definition of Quartiles only.
