# Mean of a Frequency Distribution TI-84 | TI-83 Example

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.
