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!)

In a scatterplot, an outlier...

• ...is something we didn't learn 8th grade

• ...is always the first point in the scatterplot

• ...is a point that is far outside the main cluster of points/ordered pairs

• ...is always the middle point in the scatterplot

What conclusion may we make from the scatter plot?

• The more books students read, the lower their English grade.

• The more books students read, the higher their English grade.

• The fewer books students read, the higher their English grade.

• No relationship exists between the number of books students read and their English grades.
