Outlier and Cluster Scatter Plot

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.

Identify the clusters, correlation, and outliers in the scatter plot.

• There is a cluster between 250 and 750 on the x-axis, an outlier at (1500, 53,000) and this is a positive correlation.

• There is a cluster between 0 and 250 on the x-axis, an outlier at (1500, 53,000) and this is a negative correlation.

• There is a cluster between 500 and 750 on the x-axis, an outlier at (1500, 53,000) and this is a positive 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

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
