This multiple-case study research design examined three WIA out-of-school youth workforce development programs in Southern Nevada, with out-of-school youth participants as the embedded units of analysis. Yin describes two types of Single Case studies – Holistic (single unit of analysis) and embedded (multiple units of analysis). A (VERY) BRIEF REFRESHER ON THE CASE STUDY METHOD 7 study. Problem might arise when the entire nature of the case study shifts, during the course of the study. At the same time, case studies also can have nested units within the main ... or multiple cases—what then might be labeled as a single-or a multiple-case study. The researcher might have orientated his or her study (guided by Miscellaneous: closed or adaptive design: ok to change research design if initial suppositions The single case may focus on/employ a single unit of analysis or multiple units of analysis. consider what the case is. The case serves as the main unit of analysis in a case . must follow a “replication” design . •Example: case study of how was the life history of a person; Unit of analysis or case can be “the individual” Can be the same as “case” in holistic single and multiple case study •Example: case study of how a group of software immigrants naturalize, Units of analysis… Yin (1994) describes single and multiple case designs. Asking This points to the important difference between what Yin refers to as an ‘holistic’ case design, with a single unit of analysis, and an ’embedded’ case design with multiple units of analysis (Yin, 2009: 50-52). Units of analysis are the objects of study within a research project. On the other hand, you could study student preparation for final exams by interviewing students in which the unit of analysis is the department and the unit of observation is still individual. One rationale for these designs is to identify an extreme or unique case. A researcher might choose single-case study with single unit of analysis (holistic single-case design) over other method due to its convenience (only one unit of analysis is needed!). In this case, both are individual. Specifically, Yin’s typology consists of two types of single-case designs – a type with one unit of analysis (Type 1) and a type with multiple units of analysis (Type 2) – and two types of multiple-case designs – those with one unit of analysis (Type 3) and those with more than one (Type 4). In the second study, your goal might be to compare how different departments prepare so your analysis will focus on how the departments are similar or different. The matrix then shows that single- and multiple-case studies reflect different design situations and that, within these two variant, there also can be unitary or multiple units of analysis. CHAPTER 1. case studies for several reasons. In sociology, the most common units of analysis are individuals, groups, social interactions, organizations and institutions, and social and cultural artifacts.In many cases, a research project can require multiple units of analysis. The case is defined by Miles and Huberman (1994) as, “a phenomenon of some sort occurring in a bounded context. The case is, “in effect, your unit of analysis” (p. 25). Part of the intensity is related to the fact that in case studies, data analysis begins in the field during data collection as notes are recorded, initial interpretations are the unit of analysis, and have used the case study method to develop rich and comprehensive understandings about people. This may sound simple, but determining what the unit of analysis (case) is can be a challenge for both novice and seasoned researchers alike. Embedded and holistic case studies — unit of analysis is key Multiple case typologies: can be seen as more robust than individual case studies . Typical concerns with conducting case studies are the intensity of the data collection process and the overload of information obtained.
