Final answer:

Operational definitions are essential in research to transform abstract concepts into measurable variables. Validity is achieved through operational definitions, ensuring objective measurement. Identifying and defining variables, whether quantitative or categorical, is crucial in research design.


Explanation:

Operational definitions are crucial in research as they provide a precise way to measure abstract concepts by transforming them into observable and measurable variables. For example, in psychology, depression can be operationally defined as scores on a depression scale or the number of depressive symptoms.

Researchers aim for validity by ensuring that their study measures what it is intended to measure. By providing an operational definition, researchers can objectively measure concepts and collect data in a replicable manner.

Identifying and defining variables is a fundamental step in research design. Variables can be quantitative (e.g., height) or categorical (e.g., chosen major), and operational definitions help researchers measure these variables effectively.
