Firstly, prepare the cumulative frequency table.

Class Interval |
No. of students |
Less than |
Cumulative frequency |
Suitable points |

0-4 | 2 | 4 | 2 | (4, 2) |

5-9 | 6 | 9 | 8 | (9, 8) |

10-14 | 10 | 14 | 18 | (14, 18) |

15-19 | 5 | 19 | 23 | (19, 23) |

20-24 | 3 | 24 | 26 | (24, 26) |

Now, plot the less than ogive using the suitable points.
