The question describes a process in quantitative psychological research where numbers are assigned to a phenomenon using specific rules and standard procedures. The key aspect is that these procedures allow different researchers to observe the same construct in the same way. Step 1: Analyze the core components of the description. "numbers are assigned to a phenomenon according to specific rules": This refers to the act of quantification and measurement. "using standard procedures": This implies a defined, consistent method. "that allow different researchers to observe the same construct in the same way": This is crucial. It highlights the need for a clear, unambiguous definition of how an abstract concept (construct) will be observed and measured, ensuring consistency and replicability across studies and researchers. Step 2: Evaluate the given options in light of the description. a. Measurement: This is the general process of assigning numbers to observations according to rules. While the description involves measurement, the emphasis on "standard procedures that allow different researchers to observe the same construct in the same way" points to a more specific concept. b. Quantification: This is the act of expressing something as a number or quantity. It's a part of measurement but doesn't fully capture the idea of standard procedures for consistent observation across researchers. c. Construct: A construct is an abstract concept (e.g., intelligence, anxiety) that is not directly observable. The question describes how we study or assign numbers to* a phenomenon, which might be a construct, not what a construct itself is. d. Operationalisation: This is the process of defining an abstract concept (construct) in terms of observable and measurable events. An operational definition specifies the exact procedures and methods that will be used to measure a variable. This is precisely what allows "different researchers to observe the same construct in the same way" because they are all using the same, clearly defined set of procedures. Step 3: Determine the best fit. The description emphasizes the establishment of "specific rules" and "standard procedures" to ensure that a construct can be consistently observed and measured by different researchers. This is the primary purpose and definition of operationalisation. It's the step where you translate an abstract idea into a concrete, measurable variable. The final answer is d. Operationalisation.
