What is a pie graph?

Back

A pie graph, or pie chart, is a circular statistical graphic that is divided into slices to illustrate numerical proportions. Each slice represents a category's contribution to the whole.

How do you read a pie graph?

Back

To read a pie graph, look at the size of each slice to understand the proportion of each category relative to the total. Larger slices represent larger portions.

Front

What does each slice in a pie graph represent?

Back

Each slice in a pie graph represents a part of the whole data set, showing the relative size of each category.

Front

What is the purpose of using a pie graph?

Back

The purpose of using a pie graph is to visually represent data and make it easier to compare parts of a whole.

Front

What is the total percentage represented in a pie graph?

Back

The total percentage represented in a pie graph is always 100%.

Front

How can you determine the least popular category in a pie graph?

Back

You can determine the least popular category by identifying the smallest slice in the pie graph.

Front

What is the difference between a pie graph and a bar graph?

Back

A pie graph shows parts of a whole, while a bar graph compares different categories using rectangular bars.

Front

What type of data is best represented by a pie graph?

Back

Pie graphs are best for categorical data where you want to show the proportion of each category to the whole.

Front

How do you convert a fraction to a percentage for a pie graph?

Back

To convert a fraction to a percentage, divide the numerator by the denominator and multiply by 100.

Front

What is a common mistake when interpreting pie graphs?

Back

A common mistake is to assume that all slices are equal in size without checking the actual proportions.
