Mathematics Solutions for Class 7 Math Chapter 7 Joint Bar Graph from www.meritnation.com

As students progress through their education, they are introduced to various mathematical concepts, including graphs. One such graph is the joint bar graph, which is commonly taught in class 7. In this article, we will explore the concept of joint bar graphs in detail, providing tips, examples, and tutorials to help students understand this topic better.

What is a Joint Bar Graph?

A joint bar graph, also known as a double bar graph, is a graphical representation of data that compares two sets of data. It is composed of two bars that are placed side by side and used to compare the frequency or quantity of two different categories. Students learn to create joint bar graphs to represent data that has two variables or categories.

How to Create a Joint Bar Graph?

The process of creating a joint bar graph is relatively simple. The following steps can guide students in creating one:

Select the two categories to be compared.

Draw two parallel bars for each category.

Label the x-axis and y-axis with the appropriate categories and units.

Plot the data for each category onto the corresponding bar.

Add a legend to the graph to explain the categories and colors used.

Once the graph is complete, students can analyze the data and draw conclusions based on the comparison of the two categories.

Examples of Joint Bar Graphs

Let's take a look at some examples of joint bar graphs:

Example 1: A class teacher wants to compare the number of boys and girls who scored an A grade on their recent math test. The joint bar graph below represents the data:

From the graph, we can conclude that more girls scored an A grade than boys.

Example 2: A survey was conducted to ask students about their favorite subjects. The joint bar graph below represents the data:

From the graph, we can conclude that more boys prefer mathematics, while more girls prefer English.

Tips for Creating Joint Bar Graphs

To create an effective joint bar graph, students should keep the following tips in mind:

Choose appropriate categories to compare.

Use different colors or patterns to differentiate between the two categories.

Ensure that the graph is labeled correctly with the appropriate categories and units.

Use a grid to make it easier to read and compare values.

Include a title, axis labels, and legend to make the graph easy to understand.

Tutorial: Creating a Joint Bar Graph in Excel

Creating a joint bar graph in Excel is straightforward. The following tutorial outlines the steps involved:

Open Microsoft Excel and enter the data into two columns.

Select the entire data range.

Click on the 'Insert' tab and select 'Bar Chart' from the 'Charts' section.

Select 'Clustered Bar' from the options that appear.

The joint bar graph will be created, and students can customize the graph by adding titles, axis labels, and legends.

Excel is a powerful tool that can help students create professional-looking joint bar graphs quickly and easily.

Conclusion

Joint bar graphs are an essential tool for students to learn as they progress through their education. By comparing two sets of data, students can draw conclusions and make informed decisions based on the results. This article has provided a comprehensive guide on joint bar graphs, including examples, tips, and tutorials to help students understand this topic better.
