a correspondence / to correspond / corresponding A
correspondence is a link

If the correlation is negative, it means that when one thing goes up, the other thing goes down. So, perhaps you'll find a negative correlation between the amount of time spent watching TV and success at university. The most common statistical calculations used to show correlation are Pearson's rho and Spearman's rho (you'll learn about these when you study research methods).

It could be that success causes people to be confident or that both self-confidence and success have a common cause - for instance, family background.
