Question

Quizplus · Accepted Answer

An operational definition is a clear, concise description of how a variable is going to be measured in a particular study. In this case, Dr. Jones is defining room lighting as either dimly lit or brightly lit, which is an operational definition. A theory is a well-established explanation for a phenomenon, a hypothesis is an educated guess or prediction about the outcome of a study, and a hunch is an informal idea or intuition without any evidence to support it.
