Chance of That

This is an open investigation. It can be taken to various levels of complexity and note that the construction of non-trivial examples is, in itself, difficult.

I was looking at two seemingly random lists of 12 whole numbers chosen from 1 to 5. The sample correlation was exactly zero.
 
Convince yourself that such a list of numbers is possible. Can you get a feel for the properties of such lists?
 
Explore the properties and frequencies of such lists of numbers, perhaps varying the two numbers involved.
