Which of the following statements about pie charts is true?a)They are ...
The correct answer is option 'C': The size of each slice represents the percentage of the whole.
Pie charts are a type of graph used to display data and compare different categories or parts of a whole. They are circular in shape, resembling a pie, and are divided into slices or sectors, each representing a specific category or data point. The size of each slice is proportional to the percentage it represents in relation to the total value of the data set.
Here is an explanation of why the statement is true:
Purpose of Pie Charts:
- Pie charts are primarily used to represent the distribution or composition of a whole into its individual parts or categories. They provide a visual representation of the proportion or percentage that each category contributes to the total.
Representation of Percentage:
- The size of each slice in a pie chart represents the percentage it contributes to the whole. The larger the slice, the larger the percentage it represents, and vice versa. This makes it easy to visually compare the relative sizes of different categories.
Example:
- Let's consider an example to better understand. Suppose we have a pie chart representing the distribution of fruit preferences among a group of people. The pie chart may have slices for apples, oranges, bananas, and grapes. If the apple slice is larger than the others, it indicates that a larger percentage of people prefer apples compared to the other fruits.
Alternative Statements:
- Option 'A' is incorrect. Pie charts are not best suited for showing trends over time. Line graphs or bar graphs are more suitable for displaying trends.
- Option 'B' is incorrect. Pie charts can display multiple data series, each represented by a separate slice.
- Option 'D' is incorrect. Pie charts are commonly used to display percentages, making them suitable for such representations.
Conclusion:
- In summary, pie charts are effective in representing the distribution or composition of a whole into its individual parts. The size of each slice is proportional to the percentage it represents, allowing for easy visual comparison.
