Which is an example of operationalization?

• A. Measuring stress using a 1-10 self-report scale.
• B. Randomly sampling participants.
• C. Conducting a t-test.
• D. Collecting GPA data from transcripts.

Answer: (A)

Operationalization is turning an abstract idea into a concrete, measurable form. Measuring stress with a 1-10 self-report scale does exactly that: it takes the concept of stress and defines a specific instrument and unit to quantify it, producing data that can be analyzed and compared. The other options involve who is in the study (random sampling), what analysis is used (a t-test), or simply collecting a real-world data point (GPA) without showing how the abstract construct is defined or measured. A good operationalization also considers reliability and validity to ensure the measure actually captures stress and minimizes bias.
