Quick recall flashcards

What is no correlation?
No correlation (or zero correlation) occurs when there's no clear relationship between the variables. Points on the scatter graph appear randomly scattered with no obvious pattern.
What is correlation?
Correlation describes the relationship between two variables. It shows how one variable changes when the other variable changes, but doesn't necessarily mean one causes the other.
