Defining a variable in a manner that permits to be measured is described as: 

(A) measurement

(B) treatment

(C) operationalization

(D) analysis

Correct Ans: (C)

Explanation:
Operationalization refers to defining a variable in a measurable way. Researchers use this process to transform abstract concepts into specific, observable, and quantifiable elements. For instance, if a study examines “happiness,” researchers must define it in terms of measurable indicators like survey responses or behavioral observations.

This process plays a crucial role in research. It ensures clarity and consistency in how variables are measured and studied. Without operationalization, abstract concepts can lead to confusion or misinterpretation.

Furthermore, operationalization involves creating precise definitions and determining suitable methods for data collection. Researchers might use scales, questionnaires, or experiments, depending on the nature of the study. By doing so, they ensure reliable and valid results.

Overall, operationalization bridges the gap between theoretical concepts and practical research. It allows researchers to study complex ideas in a systematic and objective manner.
