If a scatterplot has no association then...

• ...it has no ordered pairs
• ...it has ordered pairs that have a negative pattern
• ...its ordered pairs have no predictable pattern
• ...if it makes a lion on a graph (roar!)

• ...is something we didn't learn 8th grade
• ...is a puppet with a long nose named Pinocchio
• ...is a point that is far outside the main cluster of points/ordered pairs
• ...is a really naughty point who doesn't tell the truth when outside
