Document Summary
A graphic for qualitative variables in which the variable"s distribution is displayed with solid bars separated by spaces. A distribution that has two nonadjacent categories with about the same number of cases, and these categories have more cases than any others. The most common value (for variables measured at the nominal level) or the value around which cases tend to center (for a quantitative variable) An inferential statistic used to test hypotheses about relationships between two or more categorical variables in a contingency table. A bivariate (two variable) or higher order distribution showing the distribution of one variable for each category of another variable. Often used with chi-square (x^2) test of independence to tabulate and analyze relationship between two or more categorical variables. A statistic that measures the extent to which two variables are associated but not necessarily causally related. The value that the t-statistic must exceed in order to reject the null hypothesis at a certain level of probability.
