Feedback:
A unique sampling issue in MM studies concerns whether the same people will be in both the qualitative and quantitative strands. The best strategy depends on the study purpose and the research design, but using overlapping samples can be advantageous. Indeed, a particularly popular strategy is a nested approach in which a subset of participants from the quantitative strand is used in the qualitative strand. Nested sampling does not necessarily reduce costs or risk for bias. Moreover, only a subset of participants from the quantitative strand are used in the qualitative strand, so two groups of people are still needed.
