Reading Pictographs
Pictograph: Any information represented through pictures is
called pictograph.
Collection and Recording of Data: There are different ways
of collecting and recording of information (data). We shall take up two
examples of collection of data.
Richel went to a toy shop. She counted different kinds of toys
sold in a day and noted them as follows:
|
Motor Bike
|
Dolls
|
Duck
|
Cars

The information representation represented in the form of a table given above is called Recording or tabulating of data.
The recorded data can be represented through pictures as
under:
Toys sold in a day
Let us take another example.
A child visited a garden. The garden has only fruit plants
(trees). He found that there are 6 manngo trees, 5 banana trees, 4 rose trees,
6 coconut trees 8 grapes trees. The child collected this information with him
and come back home. The child recorded this information in the form of a table
as shown below:
|
Mango trees
|
Banana trees
|
Rose trees
|
Coconut trees
|
Grapes trees

The recorded data can be represented through pictures as
shown below:
This form of representation of information facilities
answering of different types of equations related to the data for example:
(i) Name the tree which is greatest in number in the garden.
In the garden, grapes trees are greatest in number, i.e., 8
(ii) Which tree is least in number in the garden?
Rose trees are least in number, i.e., 4
(iii) How many trees are there in the garden?
There are 6 + 5 + 4 + 6 + 8 = 29 trees in the garden.
1. The number of pair of shoes sold by a shop in a week is given below. Represent the given information as pictograph using an appropriate scale.
