Mode

### Example

Find the mean of the given values.

60, 70, 80, 90, 100

Solution
60, 70, 80, 90, 100

(sum) = 60 + 70 + 80 + 90 + 100

= 130 + 170 + 100

= 300 + 100

= 400

(mean) = 4005

= 80

= 130 + 170 + 100

= 300 + 100

= 400

(mean) = 4005

= 80

### Example

Find the mean of the given values.

Solution
Score | Frequency |
---|---|

0 | 1 |

1 | 1 |

2 | 4 |

3 | 7 |

4 | 5 |

5 | 2 |

Score | Frequency | (Score)⋅(Frequency) |
---|---|---|

0 | 1 | 0 |

1 | 1 | 1 |

2 | 4 | 8 |

3 | 7 | 21 |

4 | 5 | 20 |

5 | 2 | 10 |

(sum) = 0 + 1 + 8 + 21 + 20 + 10 - [2]

= 9 + 41 + 10

= 50 + 10

= 60

n = 1 + 1 + 4 + 7 + 5 + 2 - [3]

= 2 + 11 + 7

= 13 + 7

= 20

(mean) = 6020

= 3

[2]

Find the values of (Score)⋅(Frequency).

0⋅1 = 0

1⋅1 = 1

2⋅4 = 8

3⋅7 = 21

4⋅5 = 20

5⋅2 = 10

Then add (Score)⋅(Frequency).

0⋅1 = 0

1⋅1 = 1

2⋅4 = 8

3⋅7 = 21

4⋅5 = 20

5⋅2 = 10

Then add (Score)⋅(Frequency).

[3]

Add (Frequency).
