TI-84 Calculator One-Variable Statistics

This video tutorial demonstrates how to use the one variable stats tool on the TI-84 calculator to calculate the mean and median from a frequency table. It covers entering data into the calculator, selecting the one-var stats tool, and interpreting results. The tutorial also highlights differences in using older calculator models like the TI-83. By the end, viewers will understand how to find the mean and median using the TI-84.
