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.
