TI-84 Calculator Statistics Concepts

This video tutorial demonstrates how to use the one-var stats tool on the TI-84 calculator to calculate statistical measures such as mean, median, standard deviation, minimum, and maximum. It guides users through entering data, performing calculations, and interpreting results. The tutorial also explains how to calculate the range manually, as it is not provided by the calculator.

What is the primary purpose of using the one-var stats tool on the TI-84 calculator?
