Question

Quizplus · Accepted Answer

Empirical scales are based on observations and data rather than theoretical assumptions. They are developed through empirical research methods, such as factor analysis, and are designed to distinguish between groups based on objective criteria. Rational scales, on the other hand, are developed based on theoretical assumptions and often rely on subjective judgments. Factor-analytic scales are a type of empirical scale that use factor analysis to identify underlying dimensions of a construct, while orthogonal scales are a type of factor-analytic scale that have uncorrelated factors.
