I am doing educational research (mixed methodology), which involves responses from multiple stakeholders. Quantitative phase has 2 types of respondents and qualitative has 3 types. How can i do the sampling for the entire study?
Can you say more about what kind of research design you are using for your mixed methods? For example, sequential exploratory, sequential explanatory, or convergent?
For qualitative research, consider using heterogeneous representation from stakeholders including top, mid and low level of stakeholders. Again, the sample size can vary based on the data saturation!
David Morgan points out the type of study determines your sample issues. How will each phase of mixed methods be conducted and used? The purpose drives your choices. Please tell more specifics.
Puedes usar una selección de muestra por conglomerados. Debes definir a tu o tus sujetos en este caso, crear un perfil y seleccionar una cantidad representativa de cada conglomerado. Esto se ve en estudios de mercado, pero también se usa para extraer conclusiones en estudios de población. Actualmente estoy diseñando una investigación y usaré este método para la muestra.
Concurrent designs are probably the most difficult mixed methods design, because it is often difficult to integrate the two strands. Also, the editors of the Journal of Mixed Methods Research now recommend against using the term "triangulation" because it has taken on too many different meanings.
If your goal is to make a direct comparison of the qualitative and quantitative results, then having different sets of stakeholders will make this difficult.
