This hierarchical view, however, may be questioned. It is actually a package of techniques from which the analyst can chose and then adapts to his research question. A case study approach does not attempt at proving a generalised truth nor does it attempt at establishing a cause effect relationship but it attempts at empirical investigation of a phenomena. Die Praxis der Qualitativen Inhaltsanalyse. A case study approach is particularly chosen when there does not exist much prevalent theory about the situation.
They are also known as Likert scales. A systematic observation concludes that the number of men visiting this store are more. It is a method of study in depth rather than breadth. Similar to an interview, a survey may use close-ended questions, open-ended questions, or a combination of the two. The case study as a research method. A researcher who is engaged in ethnography is known as an ethnographer. The author argues in favor of both case study research as a research strategy and qualitative content analysis as a method of examination of data material and seeks to encourage the integration of qualitative content analysis into the data analysis in case study research.
Given this purpose and the scope of the paper, this brief description can by no means serve as an introduction to case study research. The criteria for interpreting the findings. Even though a case study may indicate that a specific circumstance is associated with a particular trait or situation, it does not mean that all cases relate to those same factors. Sampling validity refers to the usual criteria for precise sampling and correlative validity refers to the correlation with some external criterion e. Experiments are done when an investigator can manipulate behavior directly, precisely and systematically. This incorrectly confuses the case study method with a specific method of data collection, such as ethnography or participant observation. It refers to gathering information about a particular individual or a group in order to gain a holistic view about the subject of study.
Types of Data Gathered in Surveys and Interviews Surveys may measure either qualitative or quantitative data. The setting and context are an intrinsic part of the case.

Information about particular socio-cultural phenomena in a community is typically obtained from the members of that particular community. Compared to other methods of research, the case study method is rather inexpensive. Hence, qualitative content analysis might be an appropriate analysis and interpretation method for case study research. The investment required for survey data collection using online surveys is also negligible in comparison to the other methods. Data Collection in Case Studies Case studies always include multiple sources of information because the case includes multiple kinds of issues.
If this is not feasible, the researcher may collect data on participant and situational characteristics in order to statistically control for their influence on the dependent, or outcome, variable. Case study research is not used to determine cause and effect, nor is it used to discover generalizable truths or make predictions. However, its focus on real events and issues means it seldom uses unstructured data collection methods such as open-ended conversational interviewing from phenomenology, participant and nonparticipant field observation from ethnography, and the like. Besides, the analyzing of data is enhanced by reference to the existing literature and using this to raise questions about whether the researcher's findings are consistent with or different from extant research ibid. The researchers have to spend a considerable amount of time inside a community in order to make such observations. In this case, our emotion survey is reliable, but not necessarily valid.
However, great efforts have also been made to reconcile both sides or, where not possible, at least to soothe the dispute , thus providing the opportunity to exploit the advantages of both approaches and opening the way for synergy effects e.
