Interpreting Data of Scatter Plots

As x increases, y increases

• correlation coefficient

• causation

• positive correlation

• negative correlation

In a scatterplot, an outlier...

• ...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

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!)
