Question

The advantage of making a stem-and-leaf display instead of a dotplot is that a stem-and-leaf display

A. is for quantitative data, while a dotplot shows categorical data.
B. none of these
C. satisfies the area principle.
D. preserves the individual data values.
E. shows the shape of the distribution better than a dotplot.

Answer 1

D. preserves the individual data values.

A stem-and-leaf display is a graphical representation of quantitative data that preserves the individual data values, whereas a dotplot is a graphical representation of categorical or quantitative data that shows each data point as a dot.

In a stem-and-leaf display, the data values are grouped into stems and leaves, where the stem represents the larger digits of the data values and the leaves represent the smaller digits. This allows us to see the individual data values and their distribution.

Therefore, the advantage of making a stem-and-leaf display instead of a dotplot is that it preserves the individual data values, which can be useful when analyzing the data or looking for specific patterns in the data.
