Composite measure in statistics and research design refer to composite measures of variables, i.e. measurements based on multiple data items.[1]
An example of a composite measure is an IQ test, which gives a single score based on a series of responses to various questions.
Three common composite measures include:
- indexes - measures that summarize and rank specific observations, usually on the ordinal scale;[1]
- scales - advanced indexes whose observations are further transformed (scaled) due to their logical or empirical relationships;[1]
- typologies - measures that classify observations in terms of their attributes on multiple variables, usually on a nominal scale.[1]
