Multiple methods are vital to understanding development conceptualized as a dynamic, transactional process. This article focuses on the ways in which quantitative and qualitative methodologies can be combined to enrich developmental science and the study of human development, focusing on the practical questions of “when” and “how”. In particular, we highlight research situations that may be especially suited to mixing qualitative and quantitative approaches. We also discuss some of the critical choices confronting mixed quantitative / qualitative approaches in the phases of study design, sampling, construction of measures or interview protocols, and data analysis.
