The document describes several practice problems involving determining the type of relationship between different variables. The first problem involves determining the relationship between patients' age (skewed variable) and systolic blood pressure (skewed variable). The second examines the relationship between blood pressure (scaled variable) and gender (dichotomous variable). The third looks at the relationship between religious affiliation (dichotomous variable) and depression status (dichotomous variable). The fourth analyzes the relationship between age (scaled variable) and nationally ranked blood pressure (ordinal variable). Finally, the fifth considers the link between gender (dichotomous variable) and support for a proposition (dichotomous variable).
