Double bar graphs, additionally called twin bar charts, aid us to to compare or present much more than one sort of information, situations, or occasions instead of just one by utilizing bars.

You are watching: What is a double bar graph


What girlfriend see over is a dual bar chart. Take it a near look at it and also study it carefully, so friend can become familiar v its features.

After you have examined the dual bar graph above, here are a couple of good monitorings you can make indigenous the graph:

The range is on the left that the graph and it is 10 units.The title is "Scores on a fountain Test v or without Preparation"Preparation aided students come score higher on the fountain test.The shortest score without preparation is 45 and the highest score without preparation is 85.The lowest score v preparation is 55 and the highest score through preparation is 100. The students that made the most improvement are Darline, Carla, and also John. Their score improved by 15.The student who made the least improvement is Peter. Although Jetser"s score is still slow, he improved by 10 points when Peter"s score enhanced only by 5 points.

How come construct dual bar graphs

1. Decide what title you will give the graph2. Decision if you want horizontal or upright bars3. Choose a scale4. Put label top top the axes5. Attract the bars
Using the table shown below, let us construct a twin bar chart. We will certainly follow all procedures outlined above in bespeak to construct the double bar graph.

1. The title have the right to be clearly seen native the table. The is scores on a practice test (pretest) and also a test.2. We will choose vertical bars.3. Because the scores different from one an additional mostly through 5, 10, 15, or 20, it make feeling to chose a range of 10.If the variation in between scores were prefer 1, 2, 3, 4, or 5, that would have actually been much better to select a range of 1 or 2.4. We have the right to put the name of the student on the x axis and also the scores on the y axis. If us had determined to make horizontal bars, us would have actually put the surname of the college student on the y axis and the scores on the x axis.5. Finally, we draw bars. The dual bar graph is displayed below:
