Calculator Programs and Descriptions

Program

Description

Computes probabilities associated with Bayes' Rule.

BOXOUT

Constructs a modified boxplot, indicating mild and extreme outliers.

CHEBY

Constructs intervals about the mean according to Chebyshev's Theorem.

CHISQINT

Constructs a confidence interval for a population variance basedon a chi-square distribution.

CHISQTST

Conducts a hypothesis test for a population variance based on a chi-square distribution.

CIRCLE

Draws a pie chart.

COEFVAR

Computes the coefficient of variation.

CORRTEST

Conducts a hypothesis test for a population correlation based on the t and Z distribution models.

EMPRULE

Constructs three symmetric intervals about the mean according to the empirical rule.

EXP

Computes mathematical expectation and/or the expected value of a discrete random variable.

FREQDIST

Constructs a frequency distribution.

GEOMEAN

Computes the geometric mean.

GOODFIT

HYPERGEO

Computes probabilities associated with a hypergeometric random variable.

IQR

Computes the interquartile range.

KRUSKAL

Conducts a Kruskal-Wallis H-Test.

MANNWHIT

Conducts a runs test using the normal distribution model.

SIGNTEST

Conducts a sign test based on the binomial and the normal distribution models.

SPEARMAN

Conducts a hypothesis test on correlation based on Spearman's rank correlation coefficient.

SUMMDISC

Computes summary measures for a discrete random variable; mean, variance, and standard deviation.
