### 24.1 Introduction

#### 24.1.1 Numerical Data

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

e.g

#### 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.

Sol. Lets scale:

\$ represents 25 phones

#### 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.

Sol.
