Final Answer:
In a pie chart, the total percentage is always 100%, and when the total is included in the chart along with its parts, the percentage for the total will be 50% is It's a mathematical constraint to maintain balance.
Step-by-step explanation:
This is a mathematical constraint aimed at maintaining balance in the representation of data. To understand this, consider that a pie chart visually represents the distribution of a whole into its parts. Each part is expressed as a percentage of the whole.
When the whole is included in the chart, it essentially becomes one of its own parts, accounting for half of the chart (50%) while maintaining the overall completeness of the data visualization. This phenomenon can be explained further by recognizing that a pie chart is a circular representation, and the total 100% is distributed evenly around the circumference. Including the total in the chart effectively divides the circle into two equal halves, each representing 50% of the whole.
This ensures that the visual representation maintains its integrity and accurately reflects the relationship between the whole and its individual parts. Thus, the 50% for the total in a pie chart is not an arbitrary choice but a mathematical necessity for a balanced and accurate portrayal of the data.
