Final answer:
Graphical representations of data, essential in descriptive statistics, are often enhanced with narrative descriptions to better illustrate economic models and show relationships through line graphs, pie graphs, and bar graphs.
Step-by-step explanation:
Graphical representations of information, often found within the field of descriptive statistics, are commonly supplemented by narrative descriptions to convey the full context and meaning behind the data. In many instances, like in economic models, graphs can be pivotal in illustrating data visually, showing a wide range of patterns such as comparisons, trends, and apportionment. Examples of these graphical representations include line graphs, which depict the relationship between two variables, pie graphs, which show the distribution of a whole into percentages, and bar graphs, which use the height of bars to represent relationships and can be segmented to show subgroups.
