Pearson’s Correlation Coefficient (r) (VCE SSCE General Mathematics): Flashcards

Strength of linear association between numerical variables

Between -1 and +1

Variables numerical, association linear

Positive association (both variables increase together)

Perfect positive linear association

Perfect negative linear association

No linear association

$0.75 \leq r \leq 1$

$-1 \leq r \leq -0.75$

No - correlation does NOT imply causation
