Joestat wants you to help you create a **Cumulative Frequency Distribution** using your **TI-84 and TI-83 calculator** Use the following data set, Joestat wants you to enter the data into L2 and L3. In this example, use the following data set to solve the Cumulative Frequency Distribution.

{1, 2, 5, 4, 9, 4, 3, 1, 4, 6, 8, 7, 9, 6, 4, 8, 2, 1, 8, 7}

- First, enter the data into your TI-83 or TI-84 calculator

Instructions are available on how to Create a List TI-84 | TI-83.

- Second we need to create a Histogram

Instructions are available on how to create a Histogram TI-84 | TI-83 Example with a class width of 1.

- Third, create a Frequency Distribution

Instructions are available at Frequency Distribution TI-84 | TI-83 Example.

- Fourth, create the Cumulative Frequency Distribution using your TI-83 | TI-83 calculator. Sort the current data value (L2) and frequency (L3) by the data value (L2) in ascending order.

| [STAT] | [ 2 ] | [2nd] | [ 2 ] | [ , ] | [2nd] | [ 3 ] |

- Create a cumulative sum table based on what is stored in L3.

Note: You need to be on the Default Home screen, if not

| [2nd] | [MODE] |

- Enter stat mode and highlight L4.

- Create a cumulative sum column using L4.

| [ENTER] | [2nd] | [STAT] | [RIGHT] | [ 6 ] | [2nd] | [ 3 ] |

- Using L2 and L4 you can now create a cumulative frequency distribution with the information.

Cumulative Frequency (L2,L4)

Label Cumulative Frequency 1 3 2 5 3 6 4 10 5 11 6 13 7 15 8 18 9 20

###### Congratulations, you have successfully completed the Cumulative Frequency Distribution TI-84 and TI-83 example problem.
