#### Question

find the mean for the following frequency distribution:

C.I | 0-50 | 50-100 | 100-150 | 150-200 | 200-250 | 250-300 |

Freq | 4 | 8 | 16 | 13 | 6 | 3 |

#### Solution

Class interval | Frequency (f) | Cclass mark(x) | fx |

0-50 | 4 | 25 | 100 |

50-100 | 8 | 75 | 600 |

100-150 | 16 | 125 | 2000 |

150-200 | 13 | 175 | 2275 |

200-250 | 6 | 225 | 1350 |

250-300 | 3 | 275 | 825 |

Total | 50 | 7150 |

Mean= `(∑fx)/(∑ f) =7150/50=143`
