Statistics Programs for the Apple II Plus Microcomputer

This paper presents a statistical software package developed for use on the Apple II Plus microcomputer, modified with the Apple Pascal language card. The program addresses the following: determination of confidence intervals for single and bivariate populations; hypothesis testing for one and two parameters; computation of cumulative distributive values for the Normal, Student's T, Chi-square, F, Binomial and Poisson distributions; computation of quantile values for the Normal, Student's T, Chi-square and F distributions. The program also has the capability to store, retrieve, and modify data for use with the statistical procedures. The program was written in UCSD Pascal, which because of its portability indicates that little or no modification would be required to use it with other computers which are UCSD Pascal compatible. In addition, because of Pascal's block structure, the program can be easily modified or enhanced to include other statistical procedures which are of interest to the user. (Author)
