where are all the math people!!!

Out for lunch. I don't know, is there a particular answer you're looking for? Because there does indeed not seem to be any correlation...?

lets say you have some date like

x - y
1 - 5
2 - 5
3 - 5
4 - 5
5 - 5

so y=5

the formula for the line would be y=0*x +5

the question is would you call that line linear correlated?.

the formula describes the line perfectly, but the correlation cannot be calculated on my calc ( I think it is zero )

The thing you have done by assuming a straight line through all those points is linear interpolation. But, correlation between X and Y is zero because the value of Y stays at 5 no matter what the value of X is.

Thanks a lot YCH

just what I was looking for
