Correct Answer Explanation
Pie charts usually are not drawn with absolute values. The values of each category are first expressed as percentage of the total value of all the categories.
Key Points:
- Step 1: Convert absolute values to percentages.
- Step 2: Multiply each percentage by 3.6° to get angular component.
- The circle is divided into as many parts as there are components.
- Data represented by a component bar diagram can also be represented by a pie chart.
Why Other Options Are Wrong
- A. Absolute values: Pie charts are not drawn with absolute values directly.
- C. Ratios: Ratios are not the standard conversion for pie charts.
- D. Logarithmic values: Logarithms are not used in pie diagram construction.
