Document Summary
Determining the properties of a bivariate relationship: existence, strength, and direction. Understanding how to elaborate the relationship between variables: non-spuriousness, intervening, and conditional relationships. Strength of relationship: the larger the percentage difference across the categories, the stronger the association. Direction of relationship: when both the independent variables and dependent variables in a bivariate table are measured at the ordinal or interval-ratio level, the relationship can be either positive or negative, positive relationship. A bivariate relationship between two variables measured at the ordinal level or higher in which the variables vary in the same direction: negative relationship. A bivariate relationship between two variables measured at the ordinal level or higher in which the variables vary in opposite directions. Elaboration: a process designed to further explore a bivariate relationship; it involves the introduction of control variables, three primary goals: Elaboration allows us to test for nonspuriousness to establish cause-and-effect relations.
