In lesson 17, we have defined mixed method research as that type of research where a researcher mixes quantitative and qualitative designs either concurrently or sequentially. This lesson is a continuation of lesson 17 where we are discussing the MMR designs or strategies. These are the designs that a research may employ to collect both quantitative and qualitative data in a single study or a series of studies. MMR grew from the concept of methodological triangulation which refers to the use of more than one research method.

There are two key researchers who came up with the types of methodological triangulation. This is Denzin who came up with Within-methods triangulation and Between- methods triangulation. Within-methods triangulation is the same as multi-method research while between-methods triangulation is the same as mixed-method research. Morse came up with concurrent and sequential triangulation. Concurrent methodological triangulation means that the two methods are conducted simultaneously i.e. at the same time while in sequential, one design informs the other design.

With that Creswell came up with 4 factors to consider when using MMR. These are weight, timing, mixing and theories. From these 4 factors, Creswell came up with 4 MMR designs: 2 concurrent and 2 sequential. Further development led Bryman to come up with Priority-Sequence Decision Principle and from that principle, he came up with 9 MMR designs/strategies.

Watch Lesson 17 before Lesson 18 because lesson 18 is a continuation of lesson 17
