A stem-and-leaf plot is displayed. The plot is divided into two columns: "Stem" on the left, and "Leaf" on the right. The "Stem" column lists the digits in the order 0, 1, 2, 3, 4, 5, and 6, starting with 0 at the topmost column. Each digit in the "Stem" column is paired with aligned with a group of digits in the "Leaf" column. For stem 0, the leaf is

The scores are ordered.

A stem-and-leaf plot does not give an idea of outliers and clusters.

It is only appropriate for data where scores have high frequencies.

The individual scores cannot be read on a stem-and-leaf plot.
