Correlation does not imply
Causation, however correlation is observe relationships between two variables and how they vary.

There is two types of Correlations:

Positive - one variably increases as the other increases (height and weight of children, both go up and that is positive)

Neg - One variable increases and the other decreases (drug use increase and grades decreased) this is a neg

Adv of Correlation - can talk about relationships amg variables.
