Which of the following describes the total composition of a pie chart?

• A. It should add up to 50%
• B. It represents a single data point
• C. All sectors should add up to 100%
• D. It should include at least three categories

Answer: (C)

The total composition of a pie chart is accurately described by the principle that all sectors should add up to 100%. A pie chart is designed to visually represent the proportions of different categories relative to a whole. Each slice of the pie indicates a portion of the total, and together they must equal the entirety, which is symbolized by 100%. This ensures that the chart provides a clear and accurate reflection of how each category contributes to the overall data set. In contrast, adding up to 50% would not adequately represent the entirety of the data, as a pie chart must encompass all values in total. A pie chart does not represent a single data point; instead, it serves to illustrate the relationships between multiple data points as parts of a whole. Lastly, while including at least three categories can provide a more informative chart, it is not a strict requirement for constructing a pie chart; it can effectively represent two categories, provided they together sum up to 100%.
