For a different type of requirements different central tendencies are used.

Mode tells us the number of observation which occurs more frequently. The observation which occurs most of the time is called the Mode of that group.

**Example**

If we have the observation of average temperature in New Delhi for 12 months then find the month in which it has the maximum average temperature? What is the mode of the given observation?

Month | Average Temperature |

January | 18 |

February | 22 |

March | 24 |

April | 25 |

May | 25 |

June | 29 |

July | 27 |

August | 27 |

September | 27 |

October | 25 |

November | 21 |

December | 19 |

**Solution**

As you can see that the maximum average temperature is in the month of June.

Its mode will be 27 as it occurs more frequently i.e. three times.

**Mode of a Large Number of Observations**

If the number of observations is very large then we can convert the data in the tabular form using frequencies and tally marks. Then it will be easy to find the mode of the given data.

So you can check the number of observation which has a large number of frequency is the mode of that group.

**Example**

Find the mode of the data of scores obtained by students of class 7 in Sanskrit given below.

**Solution**

As you can see that the maximum average temperature is in the month of June.

Its mode will be 27 as it occurs more frequently i.e. three times.

**Mode of a Large Number of observations**

If the number of observations is very large then we can convert the data in the tabular form using frequencies and tally marks. Then it will be easy to find the mode of the given data.

So you can check the number of observation which has a large number of frequency is the mode of that group.

**Example**

Find the mode of the data of scores obtained by students of class 7 in Sanskrit given below.

Score | Number of Students |

2 | 4 |

4 | 2 |

8 | 3 |

9 | 2 |

11 | 5 |

13 | 4 |

15 | 6 |

18 | 8 |

**Solution**
