Step 1:I'll solve this problem step by step, focusing on the key aspects of an operational definition.
Step 2:: Understanding Operational Definitions
An operational definition is a precise, measurable description of a concept that specifies exactly how it will be observed and measured in a study. The key characteristics are: - Concrete and specific - Quantifiable - Can be directly observed or measured - Eliminates ambiguity
Step 3:: Analyzing the Options
A. "Hypotheses are educated guesses..." - This is a conceptual definition - Does not specify how to measure or observe hypotheses - NOT an operational definition B. "Class participation is the number of times a student raises his or her hand in class." - Provides a specific, countable measure - Clearly defines how participation will be observed - Can be directly measured - MEETS the criteria of an operational definition C. "Cognitive processes include perception, remembering..." - This is a theoretical description - Too broad and not measurable - NOT an operational definition D. "Reading ability can be used to predict success..." - This is a predictive statement - Does not define how reading ability is measured - NOT an operational definition
Step 4:: Reasoning
The operational definition must: - Transform an abstract concept into a measurable variable - Provide a clear method of observation - Allow for consistent measurement across different contexts
Final Answer
B is the best example of an operational definition because it provides a specific, quantifiable method of measuring class participation by counting the number of times a student raises their hand.
