# The following is the distribution of weights (in kg) of 40 persons

Weight in kg 40-45 45-50 50-55 55-60 60-65 65-70 70-75 75-80

Number of persons 4 4 13 5 6 5 2 1

Construct a cumulative frequency distribution (of the less than type) table for the data above

**Solution:**

Given, the data represents the weight of 40 persons.

We have to construct a cumulative frequency distribution of the less than type table for the data.

Weight in kg |
Number of persons |
Cumulative frequency |

Less than 45 |
4 |
4 |

Less than 50 |
4 |
4 + 4 = 8 |

Less than 55 |
13 |
8 + 13 = 21 |

Less than 60 |
5 |
21 + 5 = 26 |

Less than 65 |
6 |
26 + 6 = 32 |

Less than 70 |
5 |
32 + 5 = 37 |

Less than 75 |
2 |
37 + 2 = 39 |

Less than 80 |
1 |
39 + 1 = 40 |

**✦ Try This: **The following is the distribution of weights (in kg) of few persons:

Weight in kg | 40-45 | 45-50 | 50-55 | 55-60 | 60-65 | 65-70 | 70-75 | 75-80 |

Number of persons | 3 | 3 | 11 | 6 | 7 | 4 | 2 | 4 |

Construct a cumulative frequency distribution (of the less than type) table for the data above.
