What is a circle or a pie graph?
A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area), is proportional to the quantity it represents.
What is pie chart used for?
Pie charts can be used to show percentages of a whole, and represents percentages at a set point in time. Unlike bar graphs and line graphs, pie charts do not show changes over time.
What is pie chart and its uses?
Pie charts show the parts-to-whole relationship A pie chart is a circle that is divided into areas, or slices. Each slice represents the count or percentage of the observations of a level for the variable. Pie charts are often used in business.

What is the formula for pie chart?

How do you describe data in a pie chart?
A Pie Chart is a type of graph that displays data in a circular graph. The pieces of the graph are proportional to the fraction of the whole in each category. In other words, each slice of the pie is relative to the size of that category in the group as a whole.
How do you interpret data presented in a pie chart?
To interpret a pie chart, compare groups.
- When you interpret one pie chart, look for differences in the size of the slices.
- When you compare multiple pie charts, look for differences in the size of slices for the same categories in all the pie charts.
