What is the correlation between length of running start and distance of jump?

• positive:  the further you run the further you jump
• negative: the less you run the less distance of your jump
• positive: the further your running start the less your distance

Which scatter plot shows a linear relationship between x and y?

• All of the above

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!)
