Bar graphs tell you how much you have of different things, but that's not all they can tell you! In this lesson, we'll practice reading and analyzing bar graphs and learn how to use them to compare amounts.

Bar Graphs

You know that graphs can give us lots of information about many different things. This data, or information, helps us to learn more about our world and make decisions.

Bar graphs use colored bars to show amounts. They have an x-axis, which is a horizontal line on the bottom of the graph, and a y-axis, which is a vertical line on the left side of the graph. One axis will always show measurable values, like amounts or temperatures. The other axis will show categories, names, or other descriptions.

Types of Bar Graphs

Now, let's discuss the different ways that bar graphs can be set up.

Four Bar Graphs

On a vertical bar graph, the x-axis shows the categories or names, while the y-axis shows the measurable values.

On a horizontal bar graph, the y-axis shows the categories or names, while the x-axis shows the measurable values

A grouped bar graph is a vertical bar graph with two or more measurable values for each name or category.

On a stacked bar graph, which can be vertical or horizontal, the measurable value is broken down into two or more parts to show the different values within the category. If you look at the example, the value shows how many sugar and chocolate chip cookies each person ate, as well how many cookies each person ate in total.

Example 1

Let's use a stacked bar graph to do some practice problems, beginning with how many apples Angelica picked.

stacked bar graph

When reading a graph, you want ask yourself two questions: What information do I have? What information do I need?

In this case, we know the name (Angelica), and we want to know the measurable value (how many apples she picked). Find Angelica's name on the x-axis, then check the y-axis to find out how many apples she picked.

Angelica picked 11 apples.

Example 2

Using the same graph, let's try another one. Who picked more than 18 apples?

According to the y-axis and the bars, there's just one bar above 18. Whose name is on the x-axis below the bar?

Here, Jocelyn picked more than 18 apples.

Example 3

Last one. This is a stacked bar graph, so the measurable value is divided into two categories to give us more information.

Let's go back to Angelica. We know that she picked 11 apples in total, but how many green apples did she pick?
