Stem-Leaf Plot Skills Quiz

Given the following data set: 12, 15, 11, 11, 20, 22, 23, 15, 14, how would you create a stem-and-leaf plot?

• Stem: 1, Leaf: 1, 1, 2, 4, 5, 5; Stem: 2, Leaf: 0, 2, 3

• Stem: 1, Leaf: 2, 5, 1, 1, 0, 2, 3, 5, 4

• Stem: 1, Leaf: 1, 1, 2, 4, 5, 5; Stem: 2, Leaf: 0, 3, 2

• Stem: 1, Leaf: 2, 5, 1, 1; Stem: 2, Leaf: 0, 2, 3, 5, 4

How do you interpret the following stem-and-leaf plot? Stem | Leaf -----|----- 1 | 2, 3, 5 2 | 0, 1, 4, 7 3 | 3, 5

• The data ranges from 12 to 35.

• The data ranges from 12 to 37.

• The data ranges from 13 to 35.

• The data ranges from 12 to 35, with most data points in the 20s.
