A teaching note on variable, construct and operational definition in Research Methods: for Housing Studies students (information from perplexity.ai)

My question: "Briefly explain the terms of observable variable, unobservable variable, construct, and operational definition in the context of Research Methods in Housing Studies."

The reply: "In the context of Research Methods in Housing Studies:

• Observable variable: A characteristic or factor that can be directly measured or observed in the study, such as housing expense or living density. These variables are tangible and can be quantified through surveys or records.

• Unobservable variable: A factor that cannot be directly measured or observed but is inferred from other indicators. In housing studies, constructs like sustainable housing or subjective well-being are unobservable variables that are measured indirectly through observable variables.

• Construct: A broad, theoretical concept used in research to represent an idea or phenomenon, which may be abstract and not directly observable. For example, "sustainable housing" or "housing satisfaction" are constructs that capture complex concepts relevant to housing research.

• Operational definition: The specific process or criteria used to measure a variable or construct in a study. It transforms abstract theoretical concepts into measurable elements, specifying how variables are calculated or recorded, such as using a survey scale to measure housing satisfaction.

These terms relate hierarchically: constructs are abstract ideas; observable variables are the measurable manifestations; unobservable variables are latent factors inferred through observed data; and operational definitions specify how constructs and variables are measured empirically."
