Measurement of Constructs
Conceptualization- the mental process by which fuzzy and imprecise constructs and their constituent components are defined in concrete and precise terms
Unidimensional- constructs are those that are expected to have a single underlying dimension
Multidimensional- constructs consist of two or more underlying dimensions
Operationalization- the process of developing indicators or items for measuring constructs
Variable- constructs which are conceptualize at the theoretical level
Attributes- levels or indicators
Value- represented by each attribute
Quantitative- numeric values of attributes
Qualitative- non-numeric values of attributes
Reflective indicator- a measure that reflects and underlying construct
Formative indicator- a measure that forms or contributes to an underlying construct
Levels of measurements- also known as rating scales refer to the values that an indicator can take
Nominal scales- also called categorical scales, measure categorical data
Ordinal scales- measure rank-ordered data
Interval scales- values measured are not only rank-ordered but are also equidistant from adjacent attributes
Ratio scales- are those that have all the qualities of nominal, ordinal, and interval scales, and in addition, also have a true zero point
Binary scales- are nominal scales consisting of binary items that assume one of two possible values such as yes or no, true or false, and so on
Likert scale- very popular rating scale for measuring ordinal data in social science research
Semantic differential scale- a composite multi-item scale where respondents are asked to indicate their opinions or feelings toward a single statement using different pairs of adjectives framed as polar opposites
Guttman scale- uses a series of items arranged in increasing order of intensity of the construct of interest from least intense to most intense
Scale- an empirical structure for measuring items or indicators of a given construct
Index- a composite score derived from aggregating measures of multiple constructs called components that use a set of rules and formulas
