A rationale for the use of Mixed Methods in a research project could be which of the following: a. Qualitative surveys, being relatively expensive, are expedient to map out a broad view of issues that are potentially irrelevant to your research question, then analysed interpretively so as to widen the focus for more in-depth interviews of a quantitative nature, which are more accurate b. two or more data collection methods disregard triangulation c. themes emerging from a qualitative study never form the bases of more generalised surveys based on qualitative data d. Quantitative surveys, being relatively quick and inexpensive, are often used to map out a broad view of contextual issues that are considered potentially relevant to your research question, then analysed so as to narrow down the focus for more in-depth interviews of a qualitative nature, which are more time consuming
