arudkov is there gonna be a @line@ with no correlation for III?
ybavly @ arudkov: I think there would be a line.

QUESTION: if there is no correlation there could be any number of slopes... not necessarily 0, correct?
Teeto If there is no corellation (linear relationship) then it is not possible to explain Y using X.
The best guess for Y would be it's average value. So YBar=b0=AVG(Y), no slope and no X in the equation.
