Il corso offre un’introduzione all’analisi dei dati multivariata e alla psicometria. La prima parte del corso è incentrata sul modello lineare generale; gli argomenti specifici comprendono la regressione semplice e multipla, l’analisi della varianza/covarianza (ANOVA/ANCOVA) e i modelli misti. La seconda parte del corso presenta l’analisi fattoriale esplorativa e l’analisi delle componenti principali. Nella sezione finale vengono discussi i concetti chiave della misurazione psicologica (livelli di misura, scaling, validità, attendibilità) e le tecniche psicometriche di base per la costruzione e l’analisi degli item. Alle lezioni teoriche si affiancano esercitazioni pratiche, con gruppi di lavoro, produzione e interpretazione di output (software statistico jamovi).
The course provides an introduction to multivariate data analysis and psychometrics. The first part of the course centers on the general linear model; specific topics include bivariate and multiple regression, analysis of variance/covariance (ANOVA/ANCOVA), and mixed models. The second part introduces exploratory factor analysis and principal components analysis. The final section presents key concepts of psychological measurement (measurement levels, scaling, validity, reliability) and basic psychometric techniques of item construction and analysis. Theoretical lectures are complemented by in-class activities, with small group discussions and the production and interpretation of statistical outputs (with the jamovi app).
