Notes
Drawing a Pictograph:
The following are the details of the number of students present in a class of 30 during a week. Represent it by a pictograph.
Days | Number of students present |
Monday | 24 |
Tuesday | 26 |
Wednesday | 28 |
Thursday | 30 |
Friday | 29 |
Saturday | 22 |
With the assumptions, we have made earlier,
24 may be represented by
26 may be represented by and so on.
Thus, the pictograph would be
Example
Total number of animals in five villages are as follows:
Village A: 80
Villages B: 120
Village C: 90
Village D: 40
Village E: 60
Prepare a pictograph of these animals using one symbol ⊗ to represent 10 animals and answer the following questions:
(a) How many symbols represent animals of village E?
(b) Which village has the maximum number of animals?
(c) Which village has more animals: village A or village C?
The pictograph for the given data can be drawn as follows.
Village |
Number of animals ⊗ − 10 animals |
Village A |
⊗⊗⊗⊗⊗⊗⊗⊗ |
Village B |
⊗ ⊗ ⊗ ⊗ ⊗ ⊗ ⊗ ⊗ ⊗ ⊗ ⊗ ⊗ |
Village C |
⊗ ⊗ ⊗ ⊗ ⊗ ⊗ ⊗ ⊗ ⊗ |
Village D |
⊗ ⊗ ⊗ ⊗ |
Village E |
⊗ ⊗ ⊗ ⊗ ⊗ ⊗ |
(a) 6 symbols will represent animals of village E as there were 60 animals in this village.
(b) Village B has the maximum number of animals i.e., 120.
(c) Village A and C have 80 and 90 animals in it. Clearly, Village C has more animals.
