What does an operational definition imply about a variable?

An operational definition refers to how a variable is defined in specific, measurable terms, which is essential for conducting empirical research. This implies that the variable can be observed, manipulated, and tested through practical applications in a research context. By providing clear criteria for measurement, an operational definition allows researchers to quantify variables and ensure that different studies can be compared and replicated.

For example, if a researcher is studying "anxiety," they must specify what they mean by anxiety and how it will be measured—perhaps through a self-report questionnaire or physiological indicators. This clarity helps in ensuring that the research findings are grounded in observable phenomena, bridging the gap between theoretical concepts and real-world applications. This focus on measurable aspects is crucial for advancing scientific understanding and validating results in empirical research.
