Total number of students of a school in different years is shown in the following table Years Number of students 1996 400 1998 535 2000 472 2002 600 2004 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?"

To do:

We have to prepare a pictograph of students using one symbol to represent 100 students and answer the given questions.

Solution:

(i) 6 symbols represent total number of students in the year 2002.

(ii) 5 complete and 1 incomplete symbols represent total number of students for the year 1998.

The pictograph for the given data is as follows:

Year Number of students \( \otimes=50 \) students 1996 \( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \) 1998 \( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \) x 2000 \( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)x 2002 \( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \) 2004 \( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)\( \otimes \)x

Pictograph $B$ gives better approximations.

Therefore,

Pictograph $B$ is more informative.
