Are the observations numbers or categories, or something else?
If they are categorical, are the categories ordered?
Are we talking linear correlation or some more general association
(e.g. a monotonic relationship)? Are the variables observed over
time or space (or otherwise likely to be correlated with themselves)?
In essence, what's your model for the variables (if any)?
