Final answer:
Allen should use a clearly labeled legend and label all slices to accurately represent spending in his pie chart. Techniques like exploding slices or positioning by size should be used judiciously depending on the chart's goals.
Step-by-step explanation:
Allen should utilize presentation choices that make his pie chart clear and understandable for his readers. These include:
- Using a clearly labeled legend to identify the color for each slice, rendering it easier for readers to differentiate between the different portions of the pie chart.
- Ensuring that all slices are labeled, not just the ones that reflect service programs, to provide a complete picture of how funds are allocated by the non-profit organization.
- Avoiding techniques such as exploding the administrative overhead slice which might emphasize it unduly and mislead the viewer about its proportion of the total.
- Positioning slices in a logical order, such as starting with the largest slice at the 12 o'clock position and proceeding in descending order, could help readers understand the chart, but this should be consistent with the chart's goal of emphasizing low overhead.
These steps aim to create an accurate and transparent representation of the organization's spending, which is crucial for maintaining trust with stakeholders.
