Final answer:
An example of descriptive statistics is a run chart, which is a tool used to display trends in data visually, as opposed to a narrative report, which is not specific to descriptive statistics but may include analytical results.
Step-by-step explanation:
An example of descriptive statistics is a run chart, which is a graphical tool used to display trends in data over time. Descriptive statistics involve methods for organizing and summarizing data, such as graphing or calculating averages, to make sense of a data set. A run chart would allow us to see trends and variations in the data, facilitating an easy understanding of how the data changes. In contrast, a narrative report is not a tool specifically used within descriptive statistics but might include the results of descriptive statistical analysis.
When collecting data on the color of cars driven by students in a statistics class, a bar graph would be a better choice to display the information as it can clearly represent the frequency of each color category as separate bars.
