Combining Qualitative and Quantitative Sampling,Data Collection, and Analysis Techniques in Mixed-Method

StudiesMargarete Sandelowski*

Abstract: Researchers have increasingly turned to mixed-method techniques to expand thescope and improve the analytic power of their studies. Yet there is still relatively little direction onand much confusion about how to combine qualitative and quantitative techniques. These tech-niques are neither paradigm- nor method-linked; researchers’ orientations to inquiry and theirmethodological commitments will influence how they use them. Examples of sampling combina-tions include criterion sampling from instrument scores, random purposeful sampling, and strat-ified purposeful sampling. Examples of data collection combinations include the use of instru-ments for fuller qualitative description, for validation, as guides for purposeful sampling, and aselicitation devices in interviews. Examples of data analysis combinations include interpretivelylinking qualitative and quantitative data sets and the transformation processes of qualitizing andquantitizing. © 2000 John Wiley & Sons, Inc.
