- r>0 indicates a positive association between the variables -- the closer r gets to
1 the stronger this association is
- r<0 indicates a negative association between the variables – the closer r gets to
–1, the stronger this association is
- r=-1 and r=1 only happen when the points in the scatterplot lie EXACTLY along a straight
line r=0 indicates a weak linear association
