Stem-and-leaf displays are particularly useful for representing numerical data, such as the number of credit hours completed by the 20,000 students in this particular case. They allow for quick identification of the range and distribution of the data. A pie chart is not suitable for this type of data, as it is not categorical. A Pareto chart is typically used for analyzing the frequency or proportion of different types of problems, errors, or defects. A contingency table is useful for analyzing relationships between two categorical variables.
