The Test provides a variety of different tests based on standard
deviation based tests. They make it possible to test whether or not a
sample accurately represents the population when the standard
deviation of a population (such as the entire population of a
country) is known from previous tests.
Tests a hypothesis relative to a population mean when population
standard deviation is known.
Compares the population means of two populations when
population standard deviation is known.
Tests whether successes achieve a fixed proportion.
Compares the proportion of successes for two populations.
Used instead of the
is unknown.
Tests a hypothesis relative to a population mean when population
standard deviation is unknown.
Compares the population means of two populations when
population standard deviation is unknown.
t
Test Calculates the strength of the linear association of paired data.
Tests hypotheses concerning the proportion of samples included in
each of a number of independent groups. Mainly, the
generates cross-tabulation of two categorical variables (such as
"yes" and "no"), and evaluates the independence of the variables.
Tests hypotheses concerning the ratio of the population variance of
two populations.
Tests the hypothesis that the population means of multiple
populations are equal.
Compares the mean of one or more groups based on one
independent variable or factor.
Compares the mean of one or more groups based on two
independent variables or factors.
