Verified step by step guidance

1. Understand the context of the problem: The question is asking about a term used in experimental psychology that involves specifying steps for controlling or measuring variables.
2. Identify the key concept: The term 'operational definition' is crucial in experimental psychology as it provides a clear, precise description of how variables are measured or controlled.
3. Differentiate between the options: A 'thesis' is a statement or theory put forward to be maintained or proved, while a 'hypothesis' is a proposed explanation made on the basis of limited evidence as a starting point for further investigation.
4. Clarify the correct term: An 'operational definition' is specifically used to define how variables are measured or manipulated in an experiment, ensuring clarity and replicability.
5. Conclude with the importance: Using operational definitions allows researchers to communicate their methods clearly, ensuring that experiments can be replicated and results can be validated by others.
