Pictorial Representation of Numerical Data
The expression or illustration regarding the different information about any object or objects or activities through pictures or picture symbols is called pictorial representation or pictograph.
To create a pictograph, the following steps must be followed:
- Analyse the given numerical data.
- Determine the factors of all the numbers to be represented.
- Select an appropriate scale.
- Choose a suitable symbol.
- Organise the pictograph into appropriate columns.
- Clearly mention the scale used below the pictograph.
Example:
Information collected from 150 students about their parents’ occupations is given below. Make a pictograph based on it.
| Occupations of students’ parents | Number of students |
| Farming | 60 |
| Private Job | 20 |
| Government Job | 30 |
| Other | 40 |
All the given numbers can be divided by 2, 5, and 10. ‘ 1 picture for 10 students’ will be a convenient scale. So, we will draw 6 pictures for 60 students, 2 for 20, 3 for 30, and 4 for 40 students.
Our pictograph will look like the one given below.
Scale: 1 picture = 10 students
