Cumulative Relative Frequency Distribution TI-84 | Ti-83 Example

The Cumulative Relative Frequency Distribution is very similar to our TI-84 and TI-83 calculator.  Use the following data set and a class width of 1.  Joestat wants you to enter the data into L2 and L3.  To help you learn how to calculate the distribution, we will use the data below.
{1, 2, 5, 4, 9, 4, 3, 1, 4, 6, 8, 7, 9, 6, 4, 8, 2, 1, 8, 7}

  • Fifth, Create a cumulative relative frequency distribution storing the percentages in L5.
  • Enter stat mode and highlight l5
    Select L5 ti-84
  • Create decimals based on the information in L4 and store it in L5
    | [ENTER] | [2nd] | [ 4 ] | [ / ] | [2nd] | [STAT] | [Right] | [Right] | [ 2 ] |
