What is a bar graph?

Back

A bar graph is a visual representation of data using bars of different heights or lengths to show the quantity of each category.

Front

What do tally marks represent?

Back

Tally marks are a way to count and record numbers, where each group of five marks is represented by four vertical lines and a diagonal line across them.

Front

How do you read a bar graph?

Back

To read a bar graph, look at the height of each bar to determine the value it represents, and compare the bars to see differences in quantities.

Front

What is the purpose of a bar graph?

Back

The purpose of a bar graph is to compare different categories of data visually, making it easier to understand and analyze the information.

Front

What does the x-axis represent in a bar graph?

Back

The x-axis typically represents the categories being compared in a bar graph.

Front

What does the y-axis represent in a bar graph?

Back

The y-axis represents the values or quantities associated with each category in a bar graph.

Front

How can you find the total number of items represented in a bar graph?

Back

To find the total, add the values of all the bars together.

Front

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

Back

A bar graph uses bars to represent data, while a line graph uses points connected by lines to show trends over time.

Front

How can you determine which category has the highest value in a bar graph?

Back

Look for the tallest bar in the graph; the category represented by that bar has the highest value.

Front

What is a key in a bar graph?

Back

A key explains what each bar represents, often using colors or patterns to differentiate categories.
