TI 83 Mean and the TI 83 Median: Overview

Finding the TI 83 mean or TI 83 median from a list of data can be accomplished in two ways: by entering a list of data, or by using the home screen to type the commands. Using the list feature is just as easy as entering the data onto the home screen, and it has the added advantage that you can use the data for other purposes after you have calculated your mean and median (for example, you might want to create a TI 83 histogram).

    In step 4, you forgot to mention a crucial step. You need to input the correct list to use. For example, 1-Var Stats (L1).

    My calculations do not match yours. I have added the column on two different calculators and have gotten the same answer on each one, neither is the answer you show. Are you adding 1046 twice or once? Either way, my answers and yours do not match.

    Hi, Cindy,

    I double checked the calculations, and yes — there was a typo. Thanks for catching it (it’s now fixed).
