# The scores (out of 100) obtained by 33 students in a mathematics test are as follows:

69, 48, 84, 58, 48, 73, 83, 48, 66, 58, 84

66, 64, 71, 64, 66, 69, 66, 83, 66, 69, 71

81, 71, 73, 69, 66, 66, 64, 58, 64, 69, 69

Represent this data in the form of a frequency distribution.

**Solution:**

Number of students who have same marks in Mathematics is known as the frequency of the mark

The __frequency distribution__ table for the data is

Scores | Tally Marks | Frequency |

48 | ||| | 3 |

58 | ||| | 3 |

64 | |||| | 4 |

66 | 7 | |

69 | 6 | |

71 | ||| | 3 |

73 | || | 2 |

81 | | | 1 |

83 | || | 2 |

84 | || | 2 |

Total | 33 |

Therefore, the frequency distribution of the given data is mentioned above.
