It is believed that an unusually high occurrence of cancer in a small area may represent a "cancer cluster." Because this is rare, it is more likely to be a case of "Texas Sharpshooting." For example, suppose a person randomly shoots a gun several times at the side of a barn and draws a circle around the holes that are closest to each other. Since they fit in a 'cluster,' the person declares himself to be a Texas Sharpshooter.
Students will examine and simulate Texas Sharpshooting.
