Question

which scatterplots display an example of a cluster? check all that apply.

Explanation:

A cluster in a scatter - plot is a group of data points that are close together.

• In the second scatter - plot, the data points are spread out and there is no group of points that are close together, so it does not have a cluster.

The first and the third scatter - plots.
