| Sintesi≠ | The Semantic Differential is an attitude measurement technique that assesses the connotative meaning (emotional and evaluative associations) of concepts through ratings on multiple bipolar adjective scales. Developed by Osgood, Suci, and Tannenbaum in the 1950s, the method reveals the affective structure underlying how people perceive concepts—revealing not just what they think, but how they feel about people, brands, ideas, or policies. | Factor analysis is a statistical technique for identifying latent (unobserved) dimensions underlying observed variables, developed by Louis Leon Thurstone in the 1930s and formalized by Jöreskog (1969). Exploratory factor analysis (EFA) discovers unknown factor structure from data; confirmatory factor analysis (CFA) tests hypothesized relationships between observed and latent variables. Essential in psychometrics (test development), organizational research (measuring constructs like leadership style), and biomedicine (identifying disease subtypes), factor analysis reduces dimensionality while revealing conceptual organization in multivariate data. |
