Abstract: Mixed-Method studies have emerged from the paradigm wars between qualitative and quantitative research approaches to become a widely used mode of inquiry. Depending on choices made across four dimensions, mixed-methods can provide an investigator with many design choices which involve a range of sequential and concurrent strategies. Defining features of these designs are reported along with quality control methods, and ethical concerns. Useful resources and exemplary study references are shared. Key Words: Mixed-Methods Studies, Quantitative Research, Qualitative Research, Concurrent Strategies, and Sequential Strategies.
