Outliers and Scatter Plots

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

The scatter plot below shows John’s scores in the seven math and science chapter tests this semester. Which statement best describes the association between his math and science test scores?

• positive, linear, no outliers

• negative, linear, no outliers

• positive, linear, one outlier at (63, 99)

• negative, linear, one outlier at (99, 63)

• positive, linear, one outlier at (99, 63)

What type of association does this graph have?

• positive 

• negative

• none

• all of the above

Which description matches the scatter plot?

• Negative Association with two Clusters one between 0 and 0.5 on the x axis and the other between 0.5 and 1 on the x axis and two Outliers.

• No Association

• Positive Association with two Clusters one between 0 and 0.5 on the x axis and the other between 0.5 and 1 on the x axis and two Outliers.

• All outliers

Which table correlates to the following scatter plot?

• 
• 
• 
• 

Describe the association shown in the scatter plot.

• The scatter plot shows a positive linear association between driver age and max distance to read sign because as the age of the driver increases, the max distance to read sign increases.

• The scatter plot shows a positive nonlinear association between driver age and max distance to read sign because as the age of the driver increases, the max distance to read sign increases.

• The scatter plot shows a negative linear association between driver age and max distance to read sign because as the age of the driver increases, the max distance to read sign decreases.

• The scatter plot shows a negative nonlinear association between driver age and max distance to read sign because as the age of the driver increases, the max distance to read sign decreases.

• The scatter plot shows a no association between driver age and max distance to read sign because the age of the driver increases and the max distance to read sign show no association

Identify any outliers, gaps, or clusters.

• There are no outliers, gaps, or clusters

• Outlier at x = 12, no gaps, cluster at x = 24

• No outliers, gap between x = 3 and x = 12, cluster at x = 18

• There are no outliers, no gaps, cluster at x = 9

Identify any gaps.

• gap between x = 10 and x = 15

• gap between x = 35 and x = 40

• gap between x = 15 and x = 25

• There aren't any significant gaps in this graph.

Describe the relationship between the data.

• Positive Linear

• Negative Linear

• Non-Linear

• No Relationship

Identify any gaps.

• gap between x = 6 and x = 9

• gap between x = 18 and x = 21

• gap between x = 0 and x = 3

• There aren't any significant gaps in this graph.
