• Hypothesis: a prediction stated in a way that allows it to be tested
• operationalization: the process of translating a hypothesis into specific, testable procedures that can be measured and observed

Experimental Research

• The relationship between two or more variables is investigated by deliberately producing a change in one variable in a situation and observing the effects of that change on other aspects of the situation
