Question

Information collected from 150 students about their parent’s occupations is given below. Make a pictograph based on it.

Occupations of Students Parents	Number of students
Farming	60
Private Job	20
Government	30
Other	40

Answer 1

Hint: We start solving this question by first understanding what a pictograph means and what we use it for. Then we use the information given and consider a diagram or figure and assume that it represents 10 students. Then we represent each category with the diagrams we assumed as the number of students of that category.

Complete step by step answer:
First let us go through the definition of Pictorial representation.
Pictures and figures are made in pictograph to represent the collected data. We represent the numerical data using pictures in the Pictograph. We use them to make the representations clear and for quick understanding. In the pictographs we use the same picture to represent the number of objects.
A pictograph has a title and labelled. It helps us to compare between two types just by taking a look at the figures.
Number of students whose parent’s occupation is farming is 60.
Number of students whose parent’s occupation is a private job is 20.
Number of students whose parent’s occupation is government is 30.
Number of students whose parents occupation other than given above is 40.

Now let us consider the diagram below.
 

Let us say that it is equal to 10 students. Then we can give our pictograph as 60 students is equal to 6 figures, 20 students is equal to 2 figures, 30 students is equal to 3 figures and 40 students is equal to 4 figures.

So, the above table is our pictograph.

Note: The common mistake that one does while making pictographs is one might use different diagrams or figures to represent different categories in the pictograph. For example, while making a pictograph for the above question one might use different figures for farming, private job, government and other occupations.
