Mixed methods research (MMR) is “an approach to research in social, behavioral, and health sciences in which the investigator gathers both quantitative (closed-ended) and qualitative (open-ended) data, integrates the two, and then draws interpretations based on the combined strength of both sets of data to understand research problems.” (Creswell 2014, Concise Introduction to Mixed Methods Research)  It is rapidly becoming a popular methodology used in social and health sciences the past 30 years.

The "1+1=3" on our mug expresses the idea that the whole is greater than the sum of its parts, representing the synergy and the challenge of integrating qualitative and quantitative methods in research. Read more on the idea of "1+1=3" in MMR at the Journal of Mixed Methods Research.
