Final answer:
A pie chart is used to display data as percentages of the whole, with each slice representing a part of the total. It is essential when the focus is on understanding the proportional makeup of different segments in a whole.
Step-by-step explanation:
The tool used for displaying data that shows how all of something can be broken down into percentages of the whole is a pie chart. A pie chart illustrates the composition of a whole by dividing a circle into proportional slices or wedges, each representing a part of the total. This type of chart is particularly effective when you want to show the relative sizes of the parts to the whole. It's important to note that if a pie chart contains too many slices, it may become challenging to interpret due to the small size of some wedges.In contrast, other tools like bar charts are better suited for comparing categories or showing changes over time, where the length of each bar represents the number or percent of individuals in each category.
A line graph is good for displaying data points over time and showing trends, while a scatter plot is excellent for demonstrating the relationship between two variables.The tool used for displaying data that shows how all of something can be broken down into percentages of the whole is a pie chart.Pie charts are circular graphs that represent different categories or parts of a whole with wedges. Each wedge represents a percentage of the whole, allowing for easy comparison and understanding of how the overall group is divided.The tool used for displaying data that shows how all of something can be broken down into percentages of the whole is a pie chart.
