Bar graphs are a way to show data using bars of different lengths or heights. Each bar represents a category, and the size of the bar shows how many items are in that category.
Bar graphs help us compare data quickly. The longest bar shows the largest group, and the shortest bar shows the smallest group.
Every bar graph has important parts that help us understand the data correctly.
Always read the title and scale before looking at the bars. This will help you understand the data correctly.
To interpret a bar graph, look at the height or length of each bar and compare it to the scale. Then answer questions using the information.
When solving problems, think about words like “how many in all,” “how many more,” or “how many fewer.” These help guide your answer.
Bar graphs are often used to answer real-world questions. You can solve problems by adding, subtracting, or comparing data from the graph.
Always use the numbers from the scale to support your answer. Double-check your math to make sure your answer makes sense with the graph.
