The term "operationalization" in research design refers to the process of defining variables in measurable terms. This is a crucial step in research as it allows researchers to translate abstract constructs or concepts into specific, observable, and quantifiable elements. By operationalizing a variable, researchers can create clear definitions that facilitate measurement and ensure consistency across studies.

For instance, if a researcher is studying "anxiety," they need to specify how they will measure it. This could be through questionnaires, behavioral observations, physiological measurements, or other methods. By doing so, they enhance the reliability and validity of their research findings, as readers and other researchers can understand exactly how the construct is being assessed.

In contrast, gathering qualitative feedback, analyzing statistical data, and reviewing previous literature are essential research activities, but they do not specifically relate to the definition and measurement of variables. These processes occur at different stages of research and serve different purposes, making them distinct from the concept of operationalization.
