RegisterStatistical independence, what is it? I mean really, what is it?? [General Statistics]
Hi all,
what is statistical independence in layman's terms?? I thought I had a basic understanding of it, but now I am not so sure.
For example: Wikipedia mentions on the page for the t distribution that t=Z/s where Z and s are independent, and Z = (sample mean - mean) and s is the sample sd divided by square root of n.
Given that any perturbation on the data that changes Z will (may) also change s, I am kind of slightly conflicted regarding my own idea of independence.
I am not so much looking for a textbook explaining what it is, or a link to some web page or other. I probably read those links that are the first 50 on google and got nowhere. Rather, I am humbly looking for an explanation that appeals to my braincells, the number of which is very, very limited.
Muchas gracias.
