Case study research incorporates both qualitative and quantitative components. Often defined as “a qualitative approach in which the investigator explores a real-life, contemporary bounded system or multiple bounded systems over time through detailed, in-depth data collection involving multiple sources of information. . .. and reports a case description and case themes" (Creswell, 2011). The researcher might want to use a single case, or multiple cases depending on the research question being asked, but the case study must always be bounded by time and place to remain valid. Since case research is very interpretive, it is best practice to reflect for the reader that the case report is just one person's encounter with a complex case.
