“…In recent years, consideration of the observational methodology began as mixed method itself (Anguera and Hernández-Mendo, 2016;Anguera et al, 2017), and has expanded rapidly, as this Research Topic attests. Among the 32 published articles, there are 17 that use observational methodology, and from this point of view, the great macrostages that characterize the process are expressed through the QUAL-QUAN-QUAL, which allows qualitative data to be transformed into other types, also qualitative, but in such a way that they can be treated quantitatively, and then interpreted qualitatively (Anguera et al, 2020;Anguera et al, in press). This interpretation of mixed methods is strongly supported by the words of Creswell and Plano Clark (2007), when referring to connecting as a way of integration between qualitative and quantitative elements.…”
