Joestat wants you to use your TI-84 or TI-84 calculator to create a geometric mean using the following data set. Use L5 to enter in the data.

Example data set {105%, 106%, 108%, 112%, 98%}

- First, Convert data set to decimal.

[1.05, 1.06, 1.08, 1.12, .98}

- Second, enter the data into your TI-83 or TI-84 calculator (in our case we will use L5)
