What is a bar graph?

Back

A bar graph is a visual representation of data using rectangular bars to show the quantity of different categories. The length of each bar is proportional to the value it represents.

How do you read a bar graph?

Back

To read a bar graph, identify the categories on the x-axis and the values on the y-axis. Each bar's height or length corresponds to the value of that category.

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

Back

If one bar is significantly taller than another, it indicates that the category represented by the taller bar has a greater value or frequency compared to the shorter bar.
