# Bar Graph for Class 5 Maths

The bar graph is a visual representation of the data. Here students will learn about what is a bar graph. Bar graph images and how to draw a bar graph.

In this learning concept, the students will also learn to

- Classify the types of bar graphs.
- Evaluate the horizontal bar graph and vertical bar graph.
- Identify the advantage of bar graphs.

Each concept is explained to class 5 maths students using illustrations, examples, and mind maps. Students can assess their learning by solving the two printable worksheets given at the pageâ€™s end.

Download the bar graph worksheet for class 5 and check the solutions to the bar graph questions for class 5 provided in PDF format.

**What Is a Bar Graph?**

A bar graph is a graphical representation of data, by rectangular bars.

- Data can be represented by bars.
- In a bar graph each bar represents a number.
- The length of bars represents numerical value.
- In a bar graph, bars can be drawn vertically or horizontally.

Example:In a school, there are 15, 20, 45, and 39 students with yellow, red, blue, and green dresses, respectively. We can represent this data using a bar graph:

## To make a bar graph, we need:

**Data categories:**Type of things in the data.

**Data value:**Numerical value of each category.

**Scale:**To draw the bar with numbers by scaling.

**Title:**We need to give an appropriate title to the graph.

- In a bar graph, there should be equal spacing between the bars.

## Types of Bar Graph

Vertical Bar Graph

- In vertical bar graphs, the bars are drawn vertically to represent the data.

Example:

The number of children in five different batches of an educational institute is given below by a vertical bar graph.

Here, 1 unit length = 10 children.

From this graph, we can find

Question:

What is the number of students in Batch 3?

Answer:

From the graph, the number of students in batch 3 is 40.

Question:

The maximum number of students present in which batch?

Answer:

The maximum number of students present in batch 2, the number of students is 50.

Horizontal Bar Graph

- In the horizontal bar graph represents the data by the horizontal bars.

Example:

The data for the baking of cakes in a bakery from Monday to Saturday is shown below by a horizontal bar graph.

1 unit = 10 cakes

Question 1:

Maximum numbers of cakes baked on which day?

Answer:

Question 2:

Minimum numbers of cakes baked on which day?

Answer:

Minimum numbers of cakes baked on Monday.

How to Draw a Bar Graph?

Let us consider,

We have four different types of animals, such as cat, dog, rabbit, and hamster and the corresponding numbers are 40, 30, 10, and 70 respectively.

## The bar graph becomes as given below:

**Note: Scale: 1 unit=10 animals.**

Transformation of a horizontal bar graph to a vertical bar graph:

From this graph, we can make the table

The following table shows number of visitors to park for the months January to March

Month |
January | February | March |

Month |
150 | 300 | 250 |

Also, from the graph we have

- The greatest number of visitors come to the park in February.
- Also, the maximum number of visitors in one month is 300.
- The number of visitors that come in March is 250.
- The minimum number of visitors comes in January.
- The number of visitors that come in January is 150.

**Also, we can make the vertical graph by the similar data:**

## Advantages of bar graph

- Bar graph summaries the large set of data in simple visual form.
- Bar graph displays each category of data in the frequency distribution.
- Bar graph displays each category of data in the frequency distribution.
- The bar graph clarifies the trend of data better than the table.
- Bar graph helps in estimating the key values at a glance.

The disadvantage of bar graph

- Sometimes, the bar graph fails to reveal the patterns, cause, effects, etc.
- It can be easily manipulated to yield fake information.
