A nonparametric test designed to understand the frequency distribution of a single categorical variable or find a relationship between two categorical variables
chi-square
A frequency table that shows the frequency of each category in one variable, contingent upon the specific category or level of the other variable
contingency table
the mean of the sampling distribution of the statistic
expected values
the total values for a single category of one variable, added up across levels of the other variable
marginal values
Tests in which there are no population parameters to estimate or distributions to test against
nonparametric tests
A chi-square test that assesses whether the observed frequencies in a sample fit the frequencies in a known distribution
test for goodness of fit
