#### Question

By drawing an ogive, estimate the following frequency distribution:

Weight (kg) | 10-15 | 15-20 | 20-25 | 25-30 | 30-35 |

No.of boys | 11 | 25 | 12 | 5 | 2 |

#### Solution

Weight(kg) | No.of boys | Cumlative Frequency |

10-15 | 11 | 11 |

15-20 | 25 | 36 |

20-25 | 12 | 48 |

25-30 | 5 | 53 |

30-35 | 2 | 55 |

Number of terms=55

∴ Median =` (55+1^("th"))/2` term = `28^("th")` term

Throgh mark of 28 on the y-axis, draw a line parallel to x-axis which meets the curve at A. from A, draw a perpendiculer to x-axis , which meets x- axis at B

The value of B is the median which is 18.4 kg .
