A total number of students of a school in different years is shown in the following table:
Years | Number of Students |
1996 1998 2000 2002 2004 | 400 535 472 600 623 |
A. Prepare a pictograph of students using one symbol 
to represent 100 students and answer the following questions:
(a) How many symbols represent total number of students in the year 2002?
(b) How many symbols represent total number of students for the year 1998?
B. Prepare another pictograph of students using any other symbol each representing 50 students. Which pictograph do you find more informative?
(A) We can prepare the pictograph of the given data as follows:
YEAR | NUMBER OF STUDENTS ( |
1996 |
|
1998 |
|
2000 |
|
2002 |
|
2004 |
|
(a) Here,
We know that,
= 100 students
And, it is given that, In the year 2002, there were 600 students
Hence,
6 symbols will represent the students of the year 2002
(b) Here,
We know that,
= 100 students
And, it is given that, in the year 1998, there were 535 students
Hence,
5 complete and one incomplete symbol will represent the students of the year 1998.
(B)
YEAR | NUMBER OF STUDENTS ( |
1996 |
|
1998 |
|
2000 |
|
2002 |
|
2004 |
|
Hence,
We can observe that,
The second pictograph is more informative
