Statistics Calculator is an
easy-to-use program designed to perform a
series of basic statistical procedures
related to distributions and
probabilities. Most of the procedures are
called inferential because data
from a sample is used to infer to a
population.
The menu bar of Statistic
Calculator contains eight choices.
These represent the basic types of
operations that can be performed by the
software.
The Exit
menu item is used to exit the software.
The
Distributions
menu item is the electronic equivalent of
probability tables. Algorithms are
included for the z, t, F, and chi-square
distributions. This selection may be used
to find probabilities and critical values
for the four statistics.
The
Counts
menu item contains routines to analyze a
contingency table of counts, compute
Fisher's exact probability for two-by-two
tables, use the binomial distribution to
predict the probability of a specified
outcome, and the poisson distribution to
test the likelihood of observing a
specified number of events.
The
Percents
menu item is used to compare two
percents. Algorithms are included to
compare proportions drawn from one or two
samples. There is also a menu option to
calculate confidence intervals around a
percent.
The
Means
menu item is used to calculate a mean and
standard deviation of a sample, compare
two means to each other, calculate a
confidence interval around a mean,
compare a sample mean to a population
mean, compare two standard deviations to
each other, and compare three or more
standard deviations.
The
Correlation
menu item is used to calculate
correlation and simple linear regression
statistics for paired data. Algorithms
are included for ordinal and interval
data.
The
Sampling
menu item is used to determine the
required sample size for a study. The
software can be used for problems
involving percents and means.
The Help menu item is used to
get this on-line help.
