Atlanta area animal shelters euthanize more animals per year than most other major city shelters. The following stem-and-leaf display shows the number of homeless cats and dogs that had to be euthanized each year in the Atlanta area for the period 1985-2004.

The distribution of the number of cats and dogs that were euthanized is unimodal, ranging from 81,100 to 90,100 euthanized. The center of the distribution is at around 85,500. b. The distribution of the number of cats and dogs that were euthanized is skewed to the right, and has several modes, with gaps in between. One mode is clustered between 87,000 and 90,000 euthanized, a second mode at 84,000, and a third mode with a cluster between 81,000 and 82,000. c.The distribution of the number of cats and dogs that were euthanized is bimodal.
