Hypоtheses аnd Vаriаbles: A hypоthesis states a presumed relatiоnship between two variables in a way that can be tested with empirical data. It may take the form of a cause-effect statement, or an "if x... then y…" statement. The cause is called the independent variable; and the effect is called the dependent variable. INDEPENDENT Variable: The thing that causes change. DEPENDENT Variable: The thing that changes. Another way to think about it is "if, then" statements. INDEPENDENT: “IF” this happens DEPENDENT: “THEN” this is the outcome For example: Find the independent and dependent variables in the hypothesis statement. Hypothesis: Increasing public transportation decreases motor vehicle crashes. Can be rewritten as: If public transportation is increased, then motor vehicle crashes will decrease. Independent = increase in public transportation (this is the thing that causes change) Dependent = number of car crashes (this is the outcome, or what will be affected by increasing public transportation)
