Pie Charts, Frequency Tables, Bar Graphs

Front

What is a pie chart?

Back

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

Front

What is a frequency table?

Back

A frequency table is a way to organize data that shows how often each value occurs in a dataset.

Front

What is a bar graph?

Back

A bar graph is a chart that presents categorical data with rectangular bars, where the length of each bar is proportional to the value it represents.

Front

How do you find the difference between two values in a bar graph?

Back

To find the difference, subtract the value of one category from the value of another category.

Front

What does it mean if a bar is taller than another in a bar graph?

Back

It means that the category represented by the taller bar has a greater value or frequency compared to the shorter bar.

Front

How can you determine which category has the highest frequency in a frequency table?

Back

Look for the value with the highest count in the frequency column.

Front

What is the purpose of using pie charts?

Back

Pie charts are used to show the relative sizes of parts to a whole, making it easy to compare proportions.

Front

How do you read a bar graph?

Back

To read a bar graph, look at the height of each bar and compare it to the scale on the axis to determine the value it represents.

Front

What is the total number of categories in a pie chart?

Back

The total number of categories in a pie chart is equal to the number of slices it has.

Front

How do you calculate the percentage of a category in a pie chart?

Back

To calculate the percentage, divide the value of the category by the total value and multiply by 100.
