TI-84 Calculator Data Analysis

This video tutorial demonstrates how to use the one variable stats tool on the TI-84 calculator to find the mean and median of a data set. It covers entering data, selecting the one-var stats tool, and calculating the mean and median. Instructions for both newer and older versions of the TI-84 are provided, along with a brief explanation of manual calculations.
