Psychologically, humans find it easier to read images and interpret them. **A pictograph** is a similar means where data is recorded in form of images and these images help us to understand statistical information in a much easier way. A pictograph is also known as a pictogram, pictorial chart, picture graph, and many more.

## What Is A Pictograph?

A pictograph is a record consisting of pictorial symbols. Usually, in math, this is represented by the means of a graph or chart with symbolic figures representing a certain number of people, cars, factories, etc. This is one of the simplest ways to represent statistical data.

## Advantages Of Using A Pictograph

The advantages of pictograph are as follows:

- Help kids to associate objects with numbers.
- They help in visually formatting statistics.
- A Pictograph makes data interesting and easy to understand.
- It is useful for representing a large amount of data.

## Example of a Typical Pictograph

The manager of a Coffee Shop does a survey to find out what people think of all the sandwiches she sells. She interviews 12 regular customers asks them which sandwich is their favourite. She starts making a pictogram:

From the above example, we can make out that:

- Ham Sandwich is the most popular sandwich.
- Polony Sandwich is the least popular sandwich.

Hence, a pictograph helps us to interpret the data easily.

## How To Make A Pictograph?

Below is a step-wise guide of making a pictograph.

**Gather Statistics:**Before forming a pictograph, one must have the data on which the pictograph will be based on. You can easily find data in your textbook, or through a survey result.**Choose Your Pictorial Symbol:**The symbol can be anything, you can make it related to your data or you can choose shapes that are easy to draw.**Must Give A Key:**It is crucial to give a key in any form of data representation to inform the viewers about the unit you are showing the information about. One symbol might portray 1 unit or even 1000 units!**Draw The Pictograph:**Simply form an x-axis and a y-axis. Don’t forget to label them! You can now start adding the symbols according to the statistics.**Revise:**Revise and analyze your pictograph for any errors.

## Tips

- All the symbols must be of the same size.
- A part of a symbol can also be used to show data.

## Solved Questions Of Pictograph

Now that we are familiar with the pictograph, let’s work on some questions!

**Q. 1. The pictograph shows the amount of money raised by students of different tutor groups for a school event. Read the pictograph carefully and answer the questions that follow:**

**Complete the raised column.****Complete the pictogram for tutor group E.****How much money was raised altogether?**

**A)** As the key reads 1 circle = Rs. 10

- The Raised Column will be as such:
- Tutor Group S raised Rs. 60
- Tutor Group T raised Rs. 30
- Tutor Group E raised Rs. 45
- Tutor Group P raised Rs. 35

- The pictogram for tutor group E will have four complete circles and one half-circle representing Rs. 45.
- Total money raised by all the groups is: Rs. 60 + Rs. 30 + Rs. 45 + Rs. 35 = Rs. 170

**Q. 2. The given pictograph shows the number of books of each category present in a local library. Read and interpret the pictograph carefully and answer the questions that follow:**

**How many romance books does the library have?****What number of horror books does the library have?****How many books in total does the library have?****(Hint: Half circle = 4 books, Quarter circle = 2 books)**

**A)** According to the key given, the answer to the above mentioned questions are as follows:

- The library has 16 romance books.
- The library has 12 books in the category of horror.
- Total books in the library are 44.

**Q. 3. The number of hours of sunshine on a day, across a number of cities, is shown below. Read and interpret the pictograph carefully and answer the questions that follow**: **(Caution**: **The data is imaginative)**

**How many more hours of sunshine was there in Chennai than in Mumbai?****Ahmedabad had 9 hours of sunshine. Add a row of pictograph for Ahmedabad.**

**A)** According to the key, the answers to above questions are:

- Chennai received 4 hours more sunshine than Mumbai.
- The pictograph ow of Ahmedabad will have 4 full suns and 1 half sun representing 9 hours of sunshine.

**Q. 4. The data given below shows the number of different fruit trees on a farm. Draw a pictograph for it and answer the questions that follow:**

Name Of Fruit Tree | Number Of Trees |

Apple | 18 |

Guava | 30 |

Peach | 24 |

Pear | 12 |

**What number of peach trees are there on the farm?****How many fewer pear trees are there than the peach trees?****How many more guava trees are there than the apple trees?**

**A)** First and foremost, it is important to assign a key. As we can see from the above data, all the trees are a multiple of 6. Hence we can take our key: 1 Symbol = 6 Trees. Let’s take our symbol to be a tree. The pictograph formed is shown:

According to the pictograph, the answer to the questions are:

- Farm has a total of 24 peach trees.
- There are 12 less pear trees than farm trees.
- There are 12 more guava trees than apple trees.

**Q. 5. The following pictograph shows information about the modes of transport used by students to commute to school. Answer the following questions based on the information given:**
