In the first sense: <br /> 1. A case study is an empirical method that: <br /> • Investigates a contemporary phenomenon (the "case") in depth and within its real- <br /> world context, especially when <br /> • The boundaries between phenomenon and context may not be clearly evident. <br /> In the second sense, the features that are characteristic of the case study in practice include: <br /> 2. A case study <br /> • Copes with the technically distinctive situation in which there may be many more <br /> variable of interest than data points, and as one result <br /> • Benefits from the prior development of theoretical propositions to guide design, <br /> data collection, and analysis, and as another result <br /> • Relies on multiple sources of evidence, with data needing to converge in a <br /> triangular fashion. (Yin 2018, p. 15) <br /> The case study design is a descriptive, holistic, multi-case study design and as such, it <br /> represents a small cross section of possible public art collaborations within three specific small <br /> cities. Based upon literature review, and research of the three communities in the study, <br /> inferences will be drawn that can be applied to other situations. <br /> 3.3 Sampling and Sample Size <br /> A non-probability sample is used in this study because this study is concerned with <br /> specific roles within three specific communities. Therefore, the researcher interviewed public <br /> administrators, local officials, and other stakeholders involved with the public art collaborative, <br /> in each of the three communities. Communities were selected based upon having a self-reported <br /> public art presence within the community, and chosen to represent three different and distinct <br /> geographic situations (i.e., first-ring suburb, exurban community, and free-standing regional <br /> center). <br /> 73 <br />
