Line of Best Fit Outlier Cluster

Describe the relationship between the data. Identify any outliers, gaps, or clusters.

• Non-Linear, outlier at x = 1, gap between x = 10 and x = 12, cluster at x = 12

• No relationship, outlier at x = 6, gap between x = 8 and x = 10, no clusters

• Negative linear, outlier at x = 6, no significant gaps, no clusters.

• Negative linear, outlier at x = 1, gap between x = 10 and x = 12, cluster at x = 12

Identify any outliers.

• Outlier at x = 10

• Outlier at x = 15

• Outlier at x = 30

• There aren't any outliers in this graph.

Interpret the slope.

• The price drops by $40 for every unit.

• The price drops by $2 for every unit.

• The price was $40 in the beginning.

• The price was $2 in the beginning.

Select the statement that best describes the line.

• The line is the line of best fit.

• The line is NOT a line of best fit because it does not pass through two points.

• The line is NOT a line of best fit because it does not go through the middle of the data set.

• The line is NOT a line of best fit because it does not go through the origin.

How would you describe a strong association?

• There is not enough evidence to tell.

• The two data sets provide plenty of data.

• The data points are closely clustered around the trend line on the scatterplot.

• There are several outliers.

What are the coordinates of the outlier?

• (9,1)

• (0,3)

• (1,9)

• There is not an outlier.

Identify any outliers on this graph.

• There are no outliers on this graph.

• (6,2)

• (2,6)

• (5,14) and (1,2)

Which trend line is the best model for the data?

• Line A

• Line B

• Line C

• None of the above
