What term describes a carefully worded statement of the procedures used in a research study?

The term that best describes a carefully worded statement of the procedures used in a research study is operational definition. An operational definition specifies the exact procedures or operations that are used to measure or manipulate a variable in the study. This clarity is essential for the reproducibility of research and helps ensure that others can understand and replicate the study's methods accurately.

An operational definition transforms abstract concepts into measurable observations, making them practical for research. By detailing how variables are defined and measured, researchers provide transparency, allowing others in the scientific community to understand precisely what was done and how the results were obtained. This is crucial in validating the findings and supporting the scientific method.

The other terms, while relevant in research contexts, do not specifically focus on the procedural aspect of a study as operational definitions do. Research design refers to the overall strategy or framework for the study, the experimental framework encompasses the specific setup for experiments but is less about wording procedures, and theoretical models pertain to the conceptual understanding of phenomena rather than detailed procedural accounts.
