Lesson Transcript
Instructor: Cory Haley
We will explore the function and examples of a double bar graph. Also in this lesson you will learn to create questions and interpret data from a double bar graph.

What is a Double Bar Graph?

Many of us are familiar with a bar graph. A bar graph is a graphical display of data using single bars of various heights. A double bar graph is a graphical display of information using two bars besides each other at various heights. The bars can be arranged vertically or horizontally. We can use a double bar graph to compare two data groups.

A double bar graph has two axes. The x-axis of a double bar graph shows the categories being compared, and the y-axis represents the scale. A scale is a set of numbers that represents the data organized into equal intervals. It is important to know that all double bar graphs must have a title. The title of the double bar graph provides a general overview to the reader of what is being measured and compared. A double bar graph will also include a key. The key for a double bar graph will represent the groups being compared with two separate colors.

Examples of Double Bar Graphs

Take a moment and look at this double bar graph.

With a double bar graph, we can interpret its data to answer questions.

  • Which two groups are being compared?
    • In this double bar graph, boys and girls are being compared.
  • Which sport do the highest number of students enjoy?
    • Most students enjoy swimming, because swimming has the greatest number or students.
  • What is the amount of students for each category?
    • In the biking category, 18 students were compared (12 boys and 6 girls)
    • In the swimming category, 27 students were compared (10 boys and 17 girls)
    • In the soccer category, 23 students were compared (13 boys and 10 girls)
    • In the basketball category, 26 students were compared (17 boys and 9 girls)
    • In the Frisbee category, 23 students were compared (11 boys and 12 girls).

These are just a few questions we can answer by interpreting the data from this double bar graph.

Constructing a Double Bar Graph

As you learned earlier in the lesson, a double bar graph must have certain features. Take a look at the features of this double bar graph. Imagine you work for an ice cream company and just did a survey to find out which ice cream is the favorite among some 1st and 2nd grade students.
