Which term best describes the process of defining how a variable will be measured?

• A. Conceptualization
• B. Hypothesis formation
• C. Operationalization
• D. Theoretical framing

Answer: (C)

Operationalization is the process of turning an abstract concept into measurable terms by defining how the variable will be observed and quantified. It answers how you will measure the concept, specifying indicators, instruments, scales, and procedures. For example, if you’re studying social support, you might operationalize it with a standardized questionnaire that yields a numerical score, or by counting the number of supportive interactions per week. This step links theory to data and ensures the variable can be reliably observed and analyzed. By contrast, conceptualization is about clarifying what the concept means in theory, theoretical framing concerns the perspective guiding the study, and hypothesis formation is about proposing testable predictions.
