TI-83 Plus Calculator Programs

The table below contains a list and brief description of the TI-83 Plus calculator programs presented in the Graphing Calculator Manual to accompany Elementary Statistics, Eighth Edition, by Robert Johnson and Patricia Kuby.

Calculator Programs and Descriptions

Program

Description

BAYES

Computes probabilities associated with Bayes' Rule.

CENTRAL

Computes the midrange and mode for a data set.

CHEBY

Applies Chebyshev's theorem to a sample or population, summary statistics, or observations.

CHISQINT

Constructs a confidence interval for a population variance.

CHISQTST

Conducts a hypothesis test for a population variance.

CIRCLE

Draws a circle graph or pie diagram.

CORRTEST

Computes a confidence interval and conducts a hypothesis test for the population linear correlation coefficient.

COVAR

Computes the covariance between two samples.

CROSSTAB

Summarizes data in a cross-tabulation or contingency table.

DISCRV

Computes the mean, variance, and standard deviation for a discrete random variable.

DOTPLOT

Displays a dotplot.

FREQDIST

Constructs a frequency distribution.

GOODNESS

Conducts a goodness-of-fit test to determine how well an observed set of frequencies fits an expected set of frequencies.

GROUPBAR

Displays side-by-side bar graphs.

GROUPED

Computes (estimates of) the mean, variance, and standard deviation for data presented in the form of a grouped frequency distribution.

MANNWHIT

Conducts a Mann-Whitney U test.

PARETO

Displays a Pareto diagram for numbers and types of defects.

POSITION

Computes quartiles, percentiles, midquartile, and interquartile range for a data set.

RANDOM

Constructs a simple random sample with or without replacement.

REGINTS

In regression analysis: constructs a confidence interval for a mean response, a prediction interval for a random value, and sketches confidence interval bands and prediction belts.

RUNSTEST

Conducts a runs test for randomness of data.

SIGNTEST

Applications of the sign test: computes the position numbers for a confidence interval, constructs a confidence interval for the median of a single population, and conducts a hypothesis test concerning the median for a single population or the median difference for two dependent populations.

SPEARMAN

Computes Spearman's rank correlation coefficient and conducts a hypothesis test based on the standard normal distribution.
