Joestat wants is going to help you to calculate a Mean of the Frequency Distribution with your TI-84 or TI-83 calculator. To demonstrate we will use the data from the following table. Remember that in a frequency distribution the Data Value 1 with a Frequency 3 can also be written as {1, 1, 1}.

Use the following data set: {1 , 1, 1, 2, 2, 3, 4, 4, 4, 4, 5, 6, 6, 7 ,7 ,8 ,8 ,8 ,9 ,9}

The data set should be rewritten into a frequency table.

Data Value | Frequency |

1 | 3 |

2 | 2 |

3 | 1 |

4 | 4 |

5 | 1 |

6 | 2 |

7 | 2 |

8 | 3 |

9 | 2 |

- Enter the data into your TI-83 or TI-84 calculator

Instructions are available on the how to Create a List TI-84 | TI-83. (stored the data values into L2 and frequency in L3. - Calculate the Mean of the Frequency Distribution using 1-var stats.

###### Congratulations, you have successfully calculated the mean of a frequency distribution using your TI-84 or TI-83 calculator. You can use the same steps to complete other problems As always feel free to comment if you have any questions.

Sincerely,
