### How do I calculate one-variable statistics with frequencies on a TI-84 Plus family of graphing calculators?

The following example will demonstrate how to perform one-variable statistics with frequencies using a TI-84 Plus family of graphing calculators.

To enter the data:

1) To enter the STAT edit menu press the [STAT] key and then press the [ 1 ] key.

2) Enter the data for xList in the L1 {3,5,8,10} and Frequency list in L2 {7,2,3,1} pressing [ENTER] after each entry to move to the next line.

2) Next press the [1] key and 1-Var Stats will be typed on the home screen

3) Next in order input which lists we want to find our 1-Var Stats for, leave the List as L1, scroll down to FreqList, press the [2nd] key, then the [2] key to bring up your L2 list

4) Last press the [ENTER] key twice and the statistics will be displayed you can scroll through them using the [up arrow] key and the [down arrow] key.
