#### Question

In the tables given below, class-mark and frequencies is given. Construct the frequency tables taking inclusive and exclusive classes

Class width | Frequency |

22 | 6 |

24 | 7 |

26 | 13 |

28 | 4 |

#### Solution

Class mark | Frequency |

22 | 6 |

24 | 7 |

26 | 13 |

28 | 4 |

We have, class size = 24 - 22 = 2

Since, the lower limit of class-mark 22 = 22 - `2/2` = 21 and the upper limit = 22+ `2/2` = 23

So, the exclusive frequency table is given by:

Class | Frequency |

21-23 | 6 |

23-25 | 7 |

25-27 | 13 |

27-29 | 4 |

Also, the inclusive frequency table is given by:

Class | Frequency |

20 - 22.5 | 6 |

23 - 25.5 | 7 |

25 - 27.5 | 13 |

27 - 29.5 | 4 |

Disclaimer: The exclusive frequency table can vary from student to student. The "Class width" is replaved by "Class-marks" according to the question.
