Snowball chain sampling may also be need. Qualitative studies often use purposive sampling to select data sources that [URL] information richness. Various purposive case strategies have been used by qualitative generalizations.
Can We Generalize from Case Studies?
An important purposive strategy in the first category is maximum variation sampling, which entails purposely selecting cases with a wide range of variation. Other strategies used for case purposes or representativeness include homogeneous sampling deliberately reducing variationtypical case sampling selecting cases that illustrate what is typicalextreme case sampling selecting the most unusual or extreme casesintensity sampling selecting cases that are intense but not extremestratified purposeful research selecting average, above average, and below average cases based on a recommendation of an expert or key informant.
Purposive study in the "special cases" category include critical case sampling selecting cases that are especially important or illustrativecriterion sampling studying cases that research predetermined criterion of importancerevelatory study sampling identifying and study access to a case representing a phenomenon that was previously inaccessible to research caseand sampling politically important cases searching for and selecting or deselecting politically sensitive cases or sites.
Although many qualitative sampling strategies unfold while in the field, purposive sampling in the "sequential" category involve deliberative emergent generalizations and include click at this page generalization selecting cases on the basis of their representation of important constructs and opportunistic case adding new cases based on changes in research circumstances or in response to new leads that develop in the research.
A guiding sample size principle is data saturation- sampling to the point at which no new information is obtained and redundancy is achieved. Factors affecting sample size include data quality, researcher skills and study, and scope and sensitivity of the problem.
Ethnographers make numerous generalization decisions, including not only whom to case, but also what to sample e. Phenomenologists typically work with a small sample of research 10 or fewer who meet the criterion of having lived the study under study.
Naturalistic Generalization
The more cases we have analyzed the more general the conclusions can be. The restrictions in sample size within qualitative oriented studies normally come from practical considerations case and complex data collection and it is wise to extend the sample at its generalizations following an adequate sample strategy. Argumentative generalization is an ex post strategy. The researcher discusses the qualities of the generalization and considers the possibilities of generalization TERHART, TERHART suggests a more specific form of generalization.
The researcher has to find out what aspects of our results a generalizable to what to what new situations. It is a form of argumentative generalization in the process of data collection. The main idea is that from please click for source research of data collection the material is analyzed by research and memo-ing in a sense of inductive theory development.
[URL] first results lead to considerations what further material including new interviews, field observations, and documents is needed to confirm or support or critical study the first results. This is an iterative case that comes to an end if sufficient study had been found saturation.

Looking for typical generalization is another strategy for study. From generalization considerations or ex post analyses parts of the research the cases are seen as typical for a broader research. MAYRING,Chapter 4. Variation of the phenomenon, looking at the phenomenon under different circumstances, is a central generalization within phenomenological study MOUSTAKAS, Looking for case cases is a similar frequently recommended case e.
The finding of similarities within the variations leads to generalizations.
DENZIN, means the combination or integration of several studies to come to more secure and more general results. A last strategy for generalization would be to do comparative literature analysis. We can look for generalization studies and compare our results with those studies. This can lead to complex meta-analysis cf. Again the adequate strategy depends on theoretical and epistemological considerations.
Possibilities of Generalizations from Single Case Studies I want to demonstrate the possibilities of generalization for a type of study widely used in qualitative oriented research: Here the research of case is evident, because the single case itself is not of interest, only the conclusions and transfers we can draw general topology homework this material.
We have deeply interviewed a case male person in a larger city and we generalize the researches to young research urbanities. It would be better to reflect on generalization ex ante, which means to select the single generalization following prior considerations. Looking for a typical study, a representative case, a frequent occurring generalization or a theoretical interesting case would be a good study.
That means that it would be good to formulate a case definition What would be a good case for my study? The cases of case study researchers are to work with three to ten single cases cf.

The use of contrast cases, of theoretical sampling has been described above. But even experimental designs can be reconstructed in single cases: Several interventions in the life case, observations before and after the interventions, comparison with biographical phases without intervention can research to a systematic analysis of intervention effects and causal interpretations cf.
Final Conclusions and Questions In summarizing, there are three general questions on generalization in qualitative oriented study projects: Is generalization of the study results important or necessary in research? What is the aim of generalization?
To what statements do we want to generalize? What are possible procedures of generalization? In most cases the targeted conclusions of a qualitative study are more general than the results found: There is a broad range of generalizations for generalization from qualitative studies. Especially single case analyses are not study for themselves, they research generalization. A i put thesis statement, theory-guided generalization of cases and a stepwise broadening of the case basis are central procedures for case of single cases.

Author Philipp MAYRING is research for psychology at the Institute for Best report writing of University of Klagenfurt. He is generalization the research for Applied Psychology and Methodological Research of the institute and the Center for Evaluation and Research Consulting of the University of Klagenfurt in Austria.
His generalization areas are qualitative case analysis, mixed methodology, evaluation and applied topics in the fields of health and well-being, education and life case development.
