Casing developing cases defined by data and theory. Conceptual definition careful systematic definition of a construct that is explicitly written down. Conceptualization the process of giving an abstract construct a conceptual or theoretical definition. Operational definition defining a concept in terms empirical measures. Operationalization the translation of a construct into something real and concrete that can be empirically measured. Continuous variables the attributes can be measured on a continuum of an infinite number of values (ex: income and age; level of measurement: interval and ratio) Discrete variables the attributes can be measure with only a limited number of distinct, separate categories (categorical variables: gender, marital status, race; level of measurement: nominal and ordinal) Measurement reliability the dependability or consistency of the measure of a variable. Stability reliability does the measure yield consistent results across different points in time. Representative reliability does the measure yield consistent results across various social groups.
