Quizplus · Accepted Answer

Stem-and-leaf display is the least useful for making comparisons or showing relationships between two variables because it only displays the distribution of a single variable and does not allow for comparison or relationship between two variables. The other options (stacked bar chart, crosstabulation, scatter diagram) are all useful in displaying and comparing two or more variables.
