2. Consider the runs scored by 11 players in a match which are given below. What is the range of this given data?

8 22 64 16 32 29 16 2 7 15 1

a) 63

b) 64

c) 1

d) 223

View Answer

Explanation: Range of the data can be given by the following formula:

Range = Highest value – Lowest value

Highest value and lowest value from the data are 64 and 1 respectively.

Hence, range = 64 – 1

= 63.

3. From the table given below, what is the upper limit of class 50-55?

Mass | Students |
---|---|

40-45 | 4 |

45-50 | 12 |

50-55 | 3 |

55-60 | 2 |

60-65 | 3 |

65-70 | 1 |

Total | 25 |

a) 25

b) 52.5

c) 55

d) 60

View Answer

Explanation: Upper limit of a particular class is the highest value of that class.

In this case, the class is 50-55 and the highest value is 55.

4. From the table given below, what is the lower limit of class 65-70?

Mass | Students |
---|---|

40-45 | 4 |

45-50 | 12 |

50-55 | 3 |

55-60 | 2 |

60-65 | 3 |

65-70 | 1 |

Total | 25 |

a) 25

b) 67.5

c) 70

d) 65

View Answer

Explanation: Lower limit of a particular class is the lowest value of that class.

In this case, the class is 65-70 and the lowest value is 65.
