TI59 Statistics Programs
AN extract from Statistics Programs for the TI59 Calculator, Naval Postgraduate School, DEC 1980, 135 pgs.
ABSTRACT This paper presents a package of nine programs for the TI59 calculator. This package was developed as a solution to two problems. One problem involved expanding and modifying an existing set of programs; and a second problem involved developing five distribution approximating programs. The solution to these problems represents a package with considerable capability in computing confidence intervals, performing hypothesis tests and approximating distribution values. The distribution approximations include inverse CDF values for the Normal, Chisquare, Student's t and F distributions, which allow the computation of confidence intervals without using tables. The Tl59 proved to be a useful tool in solving these problems and demonstrated the capability of handheld programmable calculators. The comprehensive set of user guides included in this programming package provides even the inexperienced user with a stepbystep introduction to this capability. Additionally, the methods used in preparing this programming package are directly applicable to other calculators or computers. I. INTRODUCTION The purpose of this paper is to trace the development of a package of nine programs for use in the TI59 calculator … The basis for this programming effort was a set of four TI59 programs written by Professor P. W. Zehna for his personal use and later used in the classroom. Professor Zehna 's programs also computed confidence intervals and performed hypothesis testing. However, his programs were not completely userfriendly, especially in terms of user guides; and they were dependent on obtaining some percentile values from standard tables. This paper then presents a significant expansion in the scope of these early programs. The main thrust of this expansion includes a simplified and standardized set of programs and user guides, while eliminating the dependence on distribution tables. for all students of statistics (see recent 41 & 67 posts on same).

Hello!
Interesting. In 1980 it was possible to get a master's degree by writing 9 statistics programs for a Ti59 using well known formulae. Based on that most uf us here should by now have several dozen such degrees :) Cheers Max
