What types of research question(s) can best be addressed through the use of case studies? What are the advantages and disadvantages of the case study approach?
The case study approach is favored in many research studies in the social sciences, particularly sociology and anthropology. Case studies are useful in examining questions about a particular social group, and also explain phenomena with multiple causes, such as 'juvenile delinquency.' Finding ways to treat this sociological problem requires viewing particular types of juvenile delinquency in a sociological context, examining familial and social data as it relates to the behavior, and assessing how, for example, urban delinquency is different from 'small town' delinquency or how delinquency is practiced or viewed differently by various ethnic, racial, and religious subgroups. The question 'do female gang members in urban locations exhibit less violent criminal behavior than their male counterparts' might be a useful case study subject of study, although it should be supported with some statistical data as well.
There are, of course, some disadvantages to the case study approach and it is not a universally applicable methodology to all contexts. The group that is the subject of the case study may be so idiosyncratic that the findings are cannot be generalized to other groups. If one female gang is studied, this does not mean that all female gangs are alike, and the male control groups subjected to case studies may similarly be unique. Because case studies are commonly conducted through observation more than the use of quantitative analysis, the observer's personal bias, personal involvement with the subjects and personal subjectivity in general may interfere with the objectivity of the results.
Finally, the nature of the questions that can be asked and answered by the case study method cannot be retested by other experimenters or observers, as they are often particular to a group at a particular point in historical time the case study method thus is not a really 'scientific' approach, according...
Even if the findings do not meet strict methodological standards the data may be useful if it is not ethically feasible to create a strict control group and experimental design. For example, say researchers were testing a drug that could save the lives of very sick population. It might not be valid to withhold the drug from the sick population. In a quasi-experiment the researchers could test the individuals taking the drug with and compare the information they collected with information on patients with the disease who contracted the ailment before the drug was developed. This design might be used when comparing AIDS patients before and after retroviral drugs became common. Or a comparison study might be conducted between arthritis patients using a new painkilling drug with those patients using more conventional but acceptable pain-killing treatments like NSAID (non-steroidal anti-inflammatory drugs like Advil).
Pre-experimental designs might involve preliminary research, when the actual research study is uncertain. For example, say the final research will involve subjects involved in a healthy eating and exercise program in an inner city location. To determine what the program components should include and the population that might be most in need of such a program, a case study of the area might be conducted or preliminary statistical data might be gathered about the area. A true experiment consists of a control group and an experimental group, with reproducible results. This is not always the case of a pre-experimental case study or data set, or a quasi-experimental comparison of an actual experiment with data that is not a perfect control for the findings, or was not collected under the same conditions as the research findings. Ethics and a refinement of the research process may require a quasi-experimental or…
teacher instructional technology with new literacy instruction to improve elementary (K-5) student achievement in reading vocabulary? The alternative hypothesis would be that new literacy instruction does have th potential to improve elementary (K-5) student achievement in reading vocabulary. In other words that significant difference is found between classrooms that employ new literacy instructions and classrooms that do not use this method. The null hypothesis would be that no significant difference is
Second, the researcher's intense exposure to study of a case can bias the findings (the case study as a research method); at the least, there are significant opportunities for subjectivity in the implementation, presentation, and evaluation of case study research (Case studies). This high degree of subjectivity opens the door for ethical issues, particularly if the study is being sponsored by a special interest. Third, case studies involve too
Conceptually, many agree as to what constitutes a servant leader, although many variations of these characteristics can be found in the literature. The terms "servant" and "leader" may seem contradictory, which is one of the greatest barriers to operationalizing the concept of the servant leader in modern organizations. The following will examine key literature regarding the ability to operationalize the concept of the servant leader. What Distinguishes the Servant Leader? The
Conselling Master Questionnaire Describe the Boolean Approach (Hauser, 2009 p. 18) In order to use counseling databases to search for information, it is important to develop appropriate search practices. The terms one types when searching will most likely provide the results owing to their meaning. Therefore, it is up to an individual to come up with a search strategy and learn the tips of using counseling databases. The tips will assist an
E. managerial, social, political, economic benefits are linked to the study's results) the proposed helpful outcomes are realistic (i.e. dealing with questions that can actually be answered through the type of data gathering and analysis you're proposing. The suggested helpful outcomes do not go beyond the data that's to be collected). The increase in teen smoking may be abating, or may be taking a pause before it continues the climb seen
Data Analysis 1. The taster determined 11 of the 14 samples correctly. Three samples were incorrectly identified. Thus, the taster received a statistical score of 88%. 2. The results failed to support the null hypothesis. There was obviously a difference between the organic and conventional food items. 3. This output indicates that while there is a difference, the margin of 10% is too small. 4. The test indicated that for greater than 50% of
