24.1 Introduction

24.1.1 Numerical Data

=> Numerical Data: It is a collection of information in the form of Numerical figures.

e.g

Class:	I	II	III	IV	V
No. oof Students:	10	30	5	35	2

Table shown here is the Numerical data regarding class and no. of Students in a school.

24.1.2 Pictograph

=> Pictorial representation of Numerical data is done through pictures or graphs called pictorial representation of data.

=> The graph that shows pictorial representation of the Numerical data is called Pictograph.

e.g1. The following table shows the daily production of remote sets in a manufacturing company during a week.

Day	Mon	Tue	Web	Thurs	Fri	Sat
Production	25	100	75	50	50	125

Production of phone

Sol. Lets scale:

$ represents 25 phones

Day	Production
Mon	$
Tue	$$$$
Wed	$$$
Thurs	$$
Fri	$$
Sat	$$$$$

Pictograph

24.1.3 Bar Graph

=> The Numerical data is represented by rectangles of equal width with equal space between them.

=> The rectangles are called bars.

=> The bars are of various heights , drawn by selecting a particular scale.

e.g1. The table shown below shows the number of students in various classes of a school. Draw a bar graph by taking suitable scale.

Class	I	II	III	IV	V
No. of Studens	50	10	15	5	35
