Systematic review of the literature and meta-analysis in Psychology

29 Novembro 2024, 14:00 Fernando Ricardo Ferreira Santos


In this seminar, we will discuss a) the typology of literature reviews and syntheses (e.g., systematic/non-systematic, narrative/quantitative) and the advantages of systematic reviews and meta-analyses; and b) the strength of empirical evidence as function of the quality of studies and respective methodological design. We will then focus on the statistical procedures for the estimation, meta-analytic combination, and analysis of the heterogeneity of effect sizes. These features will be complemented with practical exercises.

Practical exercises on systematic review and meta-analyses.
