Correlation:Correlation refers to a statistical measure indicating how closely related two variables are without implying causation. It assesses whether changes in one variable are systematically associated with changes in another.
Positive Relationship: A positive relationship describes a situation where both variables increase together or decrease together. When one goes up, so does the other; when one goes down, so does the other.
Negative Relationship: A negative relationship describes a situation where one variable increases while the other decreases, and vice versa. When one goes up, the other goes down.
