Joestat wants you to use the class width best estimate formula on your TI84 or TI83 calculator using the following data set.

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

- Enter the data into your TI-83 or calculator

Instructions are available on the how Create a List TI-84 | TI-83. - Calculate the Class Width Formula using your TI83 or T84 calculator.

(max(L1)-min(L1))/dim(L1) - (max(L1)

[ ( ] | [2ND] | [STAT] | [RIGHT] | [RIGHT] | [ 2 ] | [2ND] | [ 1 ] | [ ) ] - -min(L1))

[ – ] | [2ND] | [STAT] | [RIGHT] | [RIGHT] | [ 1 ] | [2ND] | [ 1 ] | [ ) ] | [ ) ] - /dim(L1)

[ / ] | [2ND] | [STAT] | [RIGHT] | [ 3 ] | [2ND] | [ 1 ] | [ ) ] | [ENTER]

Congratulations, in this example you calculated the class width using the TI83 or TI84 calculator.
