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 7. For stems 1 and 2, there are no leaves. For stem 3, the leaves are 1, 3, 3, and 3. For stem 4, the leaves are 1, 2, 3, 4, and 9. For stem 5, the leaves are 1, 2, 4, 5, and 5. For stem 6, the leaf is 0. Below the plot is a row named "Key," which explains the notation. On the "Key" row, it is written that 1 | 2 = 12.

The scores are ordered.

A

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

B

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

C

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