Questions about using GT in mixed methods research

A:
What is your opinion about mix methods, such as following case study method procedure for research process and use GT for data analyis because to me data analysis in GT is more systematic compare to other methods?

Q:
If applying GT coding method (I suppose it's Strauss & Corbin's approach) helps you clarify or understand quantitative data, it's fine to use mixed methods in your research study and state that you use GT coding method to analysise data in your thesis. However, be careful that mixed methods research is much more than simply combining a qualitative method and a quantitative method. To some extent, it is not a real GT study because a GT study aims to generate a theory and mostly it's qualitative. Meanwhile, you need to reckon if it's good to title your research study as a GT study.
