Scatterplot

What are the coordinates of the outlier?

• (2,1)

• (4,3)

• (1,2)

• There is not an outlier.

What is a cluster?

• All of the points on the graph are spread out without a pattern.

• A group of points that lie close together.

• An area on the graph that contains no data.

• A data point that is set off from the other data points.

The scatter plot shows the relationship between the number of chapters and the total number of pages for several books. Use the trend line to predict how many pages would be in a book with 19 chapters. 

• 150 pages

• 170 pages

• 190 pages

• 210 pages
