## Description

The main paper purpose was to present curriculum appropriateness for requiring student use of either the TI-82 or TI-83 (Tl-82/83) in Elementary Statistics and Decision Mathematics. An Embry-Riddle student in either course formulates problems, carries out ensuing calculations, and interprets results. More high-level studies could be pursued and accomplished if intervening calculations were not as inordinately time consuming as they are for students who use only minimal-type calculators.

A further purpose was to present possibilities for use of graphing calculators without resorting to user-created programs. The TI-82/83 has features which are applicable in areas of descriptive statistics and inferential statistics taught in elementary statistics courses. In creating frequency tables, sorting data, calculating one-variable statistics, drawing histograms, and making box plots the TI-82/83 is appropriate. Procedures for making inferences about a population are taught in inferential statistics. TI-82/83 has features which are beneficial for students to use in computations necessary in carrying out hypothesis testing, generating confidence intervals, and calculating linear regression coefficients.

Applicable technology, which will improve the quality of Elementary Statistics and Decision Mathematics courses is available. Students would be well served to have the TI- 82/83 graphing calculator as an integral part of both courses.
