**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 |

#### 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 |

**Sol**. Lets scale:

$ represents 25 phones

Day | Production |

Mon | $ |

Tue | $$$$ |

Wed | $$$ |

Thurs | $$ |

Fri | $$ |

Sat | $$$$$ |

#### 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 |

Sol.
