Introduction
Case Study Case study research is an investigation of a “bounded system” or a case or multiple cases over time through detailed, in-depth data collection involving multiple sources of information (e.g., observations, audio-visual materials, reports, etc.) (Creswell, 1998). During data collection, Yin (1989) recommended six types of data collection for case studies: 1) documentation; 2) archival records; 3) interviews; 4) direct observations; 5) participant observations; and 6) physical artifacts. Case studies are bounded as they are reflective of a particular program, event, individual, or activity being studied at a particular place and time. Thus, Merriam (1988) described a case study as “an examination of a specific

There is occasionally reluctance for research consumers to give credence to the results of a case study if the message is disputed due to the limited number of subjects involved. Depending on the scope of the research, the subject studied may not be completely forthcoming with the information they provide the researcher, thus impacting the internal validity of the research. In addition, if the subjects being studied know they are being watched, they may alter their behavior, thereby causing the findings to be flawed. In addition, there may background information on a subject, which is not known as a result; may impact the results of the findings. Additionally, the researcher gives up a certain amount of their control other variables when conducting a case study. Case studies are valuable in the fact they allow detailed research to be conducted on a limited research population. Therefore, this research is very specific and in-depth and contains very detailed written records about a subject. However, this causes the report surrounding the study to become very extensive and often difficult for the reader to digest. The researcher must be cognizant of this and strive to present the material in a fashion that allows it to be deciphered. The researcher uses case study to prove their theory is correct and therefore, may be more likely to use a wide scope to interpret the data. The researcher must be
Case studies are one of the first types of research to be used in the qualitative methodology and repeating the study several times will lead to the increased reliability of the study (Starman, 2013). This methodology is appropriate because it will allow for data collection results to be generalized based on the theoretical propositions and not the population (Harrison et al. 2017).

A case study is an intensive type of research that involves a process in which detailed information is collected
1. Write a client outcome to help Mrs. Ross resolve the symptoms (i.e., defining characteristics). Refer to Section III (beginning on p. 119) of the Ackley and Ladwig text.
These two Case Studies come from a National Center on Case Studies. I think that a case study approach is very useful in applying knowledge and this is what makes you learn it better. They may be a little daunting when you read them but I will help you go through them. Please ask for help so this topic becomes more enjoyable for you.
Therefore rational for the use of case formulation is that it improves practice by linking theory, research and
There are three basic methods a researchers uses to conduct research. The first method is the observational method which is when behavior is closely observed. Now there are two different categories when it comes to the observational method- naturalistic observation and laboratory observation. When doing naturalistic observation the researcher views the participants in their natural environment. Now when doing laboratory observations the participants are viewed in a lab. Researchers have more control in a laboratory. Laboratory observations are more meaningful than those obtained with naturalistic observations. The second method is the case study method which involves an in-depth study of an individual or a group of individuals. When doing the case study method it allows the researchers to investigate a topic in way more detail than might be possible if they were trying to work with a large number of research participants. The last method that researchers use is the survey method. When using the survey method questions are administered through interviews or questionnaires. Case studies allow a researcher to investigate a topic in far more detail than might be possible if they were trying to deal with a large number of research participants.
1. To begin, assume that it is now January 1, 1993, and that each bond in Table 1 matures on December 31 of the year listed. Further, assumes that each bond has $1,000 par value, each had a 30-year maturity when it was issued, and the bonds currently have a 10 percent required nominal rate or return.
This is a case study of
In light of your reading of this study, do you think that case studies employing only a single case are helpful in advancing scientific knowledge? Explain. Are there certain areas that you are familiar with that you believe a single case study would be helpful?
An in-depth study of a particular situation rather than a sweeping statistical survey. Case study research is a method that was used to narrow down a very broad field of research into one easily researchable topic.
1. Table 8.1 shows results of an eight-center clinical trial to compare a drug to placebo for curing an infection. At each center, subjects were randomly assigned to two groups.
A case study is a puzzle that has to be solved. The first thing to remember about writing a case study is that the case should have a problem for the readers to solve. The case should have enough information in it that readers can understand what the problem is and, after thinking about it and analyzing the information; the readers should be able to come up with a proposed solution. Writing an interesting case study is a bit like writing a detective story. You want to keep your readers very interested in the situation.
Bounding a research case involves defining the breadth of the subject to study and report (Merriam, 2009). A physical parallel to bounding a problem is property fencing, which defines real estate extents (Merriam, 2009). Therefore, explaining the structure of a star may not require writing about the entire universe (Merriam, 2009). “A case study is an in-depth description and analysis of a bounded system” (Merriam, 2009, p. 40). According to Merriam, (2009), “single most defining characteristic of case study research lies in delimiting the object of study, the case” (p. 40).
Now, case studies are considered to be more of an in-depth study that uses many approaches and data sources of a solo case. Percy, Kostere, & Kostere, (2015, p. 19) stated that when we do a single case study, we do not mean a case study of one person, but instead we mean a study of a solo research/topic questions. From time to time there is a quantity of cases that are reported and studied together. The cases in a
