Analyzing Cross-Case Evidence
In Yin’s article “The Case Study Crisis”, He mentioned two potential approaches to cross-case analysis: case-survey analysis and case-comparison approach. The case comparison has to be based on the case-survey approach. The case- survey approach requires two conditions: first, isolate the factor in the case studies that catch substantial attention; second, the number of case studies has to be large enough. When these two conditions meet, we can code the factors and establish cross-case patterns. Then we can start cross-case comparisons. However, those two conditions are not always satisfactory. The number of factors is larger to the number of case studies and the extraction of factors from case study may make case study complicated. In most cases, we are lack of the case studies that needed for the data analysis. So case-survey approach has to be highly selective. The researcher must preserve the explicit citation of particular pieces of evidence when these two approaches are used.
