TI-83 Calculator Programs

The table below contains a list and brief description of the TI-83 calculator programs presented in the Graphing Calculator Manual to accompany Statistics: An Introduction, Fifth Edition, by Mason, Lind, and Marchal.

Calculator Programs and Descriptions
Program Description
BOXPLOT Displays a type (B3) boxplot, indicating mild and extreme outliers.
CCHART Displays four control charts: mean chart, range chart, percentage defective chart, and c bar chart.
CHEBY Applies Chebyshev's theorem to a sample or population, summary statistics, or observations.
CHISQINT Computes the endpoints for a confidence interval for a population variance.
CIRCLE Displays a pie chart.
COEFS Computes the coefficient of variation and the coefficient of skewness.
CORRMAT Computes the correlation matrix for a list of variables.
DISCRV Computes the mean, variance, and standard deviation for a discrete random variable.
DISPERSN Computes measures of dispersion for a sample: range, quartiles, interquartile range, and quartile deviation.
FINITPOP Computes the endpoints for a confidence interval for a population mena or a population proportion using the finite population correction factor.
FREQDIST Constructs a frequency distribution for a data set.
GOODNESS Conducts a goodness-of-fit test to determine how well an observed set of frequencies fits an expected set of frequencies.
HYPERG Computes probabilities and cumulative probabilities for a hypergeometric random variable.
KRUSKAL Conducts a Kruskal-Wallis one-way analysis of variance of ranks hypothesis test.
MEANGRP Computes the estimated mean and estimated median for data organized in a frequency distribution.
MEANS Computes measures of central tendency for a data set: trimmed mean, midrange, weighted mean, harmonic mean, geometric mean.
MODE Computes the mode for a data set.
MULTIREG Computes the regression coefficients, conducts hypothesis tests for significant regression coefficients, and constructs the ANOVA table in a multiple regression problem.
PARETO Displays a Pareto chart for numbers and types of defects.
PERMUTE Computes a generalized permutation.
PROPTEST Conducts a large-sample Z test involving two population proportions when the hypothesized difference in nonzero.
RANDOM Constructs a simple random sample with or without replacement.
RANKSUM Conducts a Wilcoxon rank-sum test to determine if two independent samples come from the same population.
REGANOVA Constructs the ANOVA table for a simple linear regression model.
REGINTS Constructs a confidence interval for a mean response, prediction interval for a random value, and displays a confidence band in a simple linear regression model.
SIGNRANK Conducts a Wilcoxon signed-rank test to compare two independent samples.
SIGNTEST Conducts a sign test based on the differences in paired observations.
SPEARMAN Conducts a test about a population correlation coefficient between ranks using Spearman's rank correlation coefficient.
TWOFACT Constructs the ANOVA table for a general two factor experiment.
VARGRP Computes estimates of range, quartiles, interquartile range, quartile deviation, sample variance, sample standard deviation, populaiton variance, and population standard deviation for data organized in a frequency distribution.
VARIABIL Computes the mean deviation, sample variance, and sample standard deviation for a data set, and the population variance and population standard deviation for a population.
VARTEST Conducts a hypothesis test involving a population variance.
