What does operationalization in experimental research involve?

• A. Developing a hypothesis for the study
• B. Identifying participant demographics
• C. Defining how variables will be measured or manipulated
• D. Establishing the duration of the study

Answer: (C)

Operationalization in experimental research is a crucial step that specifically involves defining how variables will be measured or manipulated. This process ensures that abstract concepts, such as "anxiety," "intelligence," or "satisfaction," are translated into measurable and observable variables that can be empirically tested. By clearly outlining procedures for measuring these variables, researchers can create consistent methods that enhance the validity and reliability of their study. This step is essential because without clear operational definitions, it would be difficult to determine whether the study is accurately measuring the intended constructs or the effectiveness of the experimental manipulation. The clarity provided by operationalization also aids in the reproducibility of the research, allowing other scientists to replicate the study or build on its findings effectively. Thus, defining how the variables will be measured or manipulated is foundational for conducting robust and meaningful experimental research.
