Choosing a Visualization for Income Differences
An economic analyst is preparing a presentation on income differences within a company. They initially study a small team of 5 employees and create two visualizations to show the absolute difference in income between every possible pair of individuals.
- Visualization 1: A diagram where each employee is a dot, and a line is drawn connecting every pair of dots. Each line is labeled with the income difference for that pair.
- Visualization 2: A 5x5 grid where each cell at the intersection of a row and column shows the income difference between the two corresponding employees.
The analyst now needs to expand the study to include all 300 employees in the company. Which visualization method should they choose for the larger group, and why? Justify your decision by critiquing the suitability of both methods for the expanded study.

A researcher is preparing a report on income distribution among 50 families in a small community. To illustrate the disparities, the researcher wants to visually represent every possible pairwise difference in income between the families. Which statement best analyzes the most effective way to present this specific information?
Choosing a Visualization for Income Differences
When visualizing all possible pairwise income differences within a population, a tabular format is preferred over a diagram of interconnected individuals for larger groups. The primary reason for this preference is that a table can display more precise monetary values than a diagram.
Imagine a visual representation where circles represent individuals and a straight line is drawn between every pair of individuals to represent the income difference between them. If you start with a diagram for a 4-person group and then create a new diagram for a 6-person group, what is the most accurate description of how the number of connecting lines changes?

A social scientist is analyzing income inequality and needs to present the pairwise income differences for different population sizes. Match each visualization method with the scenario where it is most effectively applied.
Analyzing the Scalability of a Visualization Method
When visually representing all possible pairwise income differences for a very large population, a diagram with points for individuals and lines for comparisons becomes impractical primarily because it becomes difficult to discern the exact income level of each individual from the diagram.
