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

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)

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
