TI-84

The TI-84 family of graphing calculators (including the TI-83) can be very useful in helping with calculating and graphing various topics in statistics and mathematics. Learn how to use the graphing calculator through video tutorial. Many different uses will be explored. Click on the categories below to move to videos for that category.

Statistics

The TI-84 family of graphing calculators can be extremely useful in Statistics.  It really speeds up the process of statistical computations.  The calculator is programmed with many commonly used statistical formulas, as well as confidence intervals and hypothesis tests.   Most of the computations in Statistics are found using technology, and the a graphing calculator is a great tool that can be taken along wherever needed.
