Dear all list members;
According to me recently discussed PhD thesis in the field of emotional design, where I have used both quantitative and qualitative research methods, as I needed to measure some emotional reaction in some of my research phases by using qualitative answers, while needed to use quantitative answers in measuring others with percentage and analyze them.
I think according to the research progress and more focused research points, the tools are used in research, the targets the researcher wants to reach, and finally the specialization and vision of the research himself, are all factors that sometimes force the researcher to use both qualitative and quantitative research methods.
Attached, you will find a very important book of Creswell, Research Design, 2nd Edd., that may help in determining the difference between qualitative and quantitative approaches, and the need to use one or both of them.
Best regards
Hamdy

Actually, Matthias, if Jerry is Historical Materialist, he can make such a statement :) When quantity reaches a threshold level, it brings about the emergence of a new quality of the object.
