Methods for testing causal relationships between phenomena and whether these relationships can be generalized across a variety of situations. A characteristic or attribute that varies, e. g. gender, age, income. A variable that has an effect on another variable. The outcome or the variable that is being caused by the iv. Possible other variable that might account for the relationship between x and y.
