topic 6 Flashcards
Concept
a family of conceptions, such as “chair”, representing the whole class of actual chairs
Direct observables
physical characteristics (sex, height, skin, color) of a person being observed and/or interviewed
Indirect observables
– characteristics of a person as indicated by answers given in a self- administered questionnaire
Constructs
level of alienation, as measured by a scale that is created by combining several direct and/or indirect observables
Conceptualization
– the mental process whereby fuzzy and imprecise notions (concepts) are made more specific and precise.
Indicator
an observation that we choose to consider as a reflection of a variable we wish to study. Thus, for example, attending religious services might be considered an indicator of religiosity
Dimension
a specifiable aspect of a concept. “Religiosity”, for example, might be specified in terms of a belief dimension, a ritual dimension, a devotional dimension, a knowledge dimension, and so forth.
Cognitive interviewing
testing potential questions in an interview setting, probing to learn how respondents understand or interpret the questions
Index
ORDINAL VALUE, a type of composite measure that summarizes and rank-orders several specific observations and represents some more-general dimension
Scale
a type of composite measure composed of several items that have a logical or empirical structure among them. Examples of scales include the Bogardus social distance
Typology
CRREATING A NOMINAL USING TWO OR MORE VARIABLES, TYPES, the classification (typically nominal) of observations in terms of their attributes on two or more variables. The classification of newspaper as liberal-urban, liberal-rural, conservative-urban, or conservative-rural would be an example.
the 3 steps
conceptualisation, operalisation, measurement
conceptionalisation
provides clarity, defines the construct in theoretical terms, specifying what it means
operionalization
definition into specific measurable criteria, how it will be observed and measured
measurement
actual process of collecting data to quantify the construct, selecting tools and methods, MEASURING
