Splitting data values into stems and leaves, such as 8|00012338, is an example of which display?

• A. Stem-and-leaf display
• B. Histogram
• C. Box plot
• D. Scatter plot

Answer: (A)

This item tests stem-and-leaf displays, which split each data value into a stem (the leading digits) and a leaf (the trailing digit). In the example 8|00012338, the stem is 8 and the leaves are 0, 0, 0, 1, 2, 3, 3, 8, which corresponds to the values 80, 80, 80, 81, 82, 83, 83, 88. This format shows the distribution while preserving the exact data points, making it easy to read off individual values and see how they cluster. A histogram bins data and loses exact values, a box plot summarizes distribution without showing each point, and a scatter plot is for relationships between two variables. Therefore, the display illustrated is a stem-and-leaf display.
