This chapter shows how planners can apply four different techniques (field research, photographic investigations, focus group research, and content analysis/meta-analysis) to access qualitative data. A mixed method research strategy provides a “big picture” understanding of questions because it incorporates qualitative and quantitative research strategies into the investigation. The chapter also shows how planners can get the “big picture” perspective by integrating the qualitative research techniques with quantitative strategies in a mixed method investigation. Mixed method research involves methodological triangulation, the use of different methods to analyze a specific situation. Mixed method research design is further broken down into two kinds of strategies: within-method and between-method triangulation. Mixed method research designs help planners better understand the complexities of life. Complementarity combines methods to measure overlapping, as well as different aspects of a situation, in order to get an enriched enhancement of that situation.
