# The following distribution gives the daily income of 50 workers of a factory

Convert the distribution above to a less than type cumulative frequency distribution and draw its ogive.

**Solution:**

The representation of cumulative frequency distribution graphically is known as a cumulative frequency curve or an ogive.

The frequency distribution table of less than type is as follows:

Daily income (in ₹) - (Upper class Limits) |
Cumulative Frequency |

Less than 120 | 12 |

Less than 140 | 12 + 14 = 26 |

Less than 160 | 26 + 8 = 34 |

Less than 180 | 34 + 6 = 40 |

Less than 200 | 40 + 10 = 50 |

Taking upper-class limits of class intervals on x-axis and their respective frequencies on y-axis, its ogive can be drawn as follows:
