What is a case-control study in research?
A case-control study is a type of observational study. It looks at 2 sets of participants. One group has the condition you are interested in (the cases) and one group does not have it (the controls). In other respects, the participants in both groups are similar.
What are different types of case-control studies?
Retrospective and Prospective Case-Control Studies
Students usually think of case-control studies as being only retrospective, since the investigators enroll subjects who have developed the outcome of interest. However, case-control studies, like cohort studies, can be either retrospective or prospective.
What is an example of a case-control study?
For example, investigators conducted a case-control study to determine if there is an association between colon cancer and a high fat diet. Cases were all confirmed colon cancer cases in North Carolina in 2010. Controls were a sample of North Carolina residents without colon cancer. The odds ratio was 4.0.
What is the difference between a case study and a case-control study?
A case report is the description of the clinical story of a single patient, whereas a case-control study compares 2 groups of participants differing in outcome in order to determine if a suspected exposure in their past caused that difference.
What is the difference between cohort study and case-control study?
Whereas the cohort study is concerned with frequency of disease in exposed and non-exposed individuals, the case-control study is concerned with the frequency and amount of exposure in subjects with a specific disease (cases) and people without the disease (controls).
Is case-control study quantitative or qualitative?
quantitative

How do you collect data in a case-control study?
Data for case-control studies is typically collected by interviewing or surveying the cases and the controls. Individuals in both groups are asked the same series of questions regarding their medical history and exposure to factors that are considered to increase the risk of developing the disease in question.
What are the advantages of a case-control study?
Advantages
- Good for studying rare conditions or diseases.
- Less time needed to conduct the study because the condition or disease has already occurred.
- Lets you simultaneously look at multiple risk factors.
- Useful as initial studies to establish an association.
What are the 3 types of cohort studies?

What are the advantages of case-control study?
Advantages of Case-Control Studies
Case-control studies have specific advantages compared to other study designs. They are comparatively quick, inexpensive, and easy. They are particularly appropriate for (1) investigating outbreaks, and (2) studying rare diseases or outcomes.
What are the 4 types of research design?
Now that we know the broadly classified types of research, Quantitative and Qualitative Research can be divided into the following 4 major types of Research Designs: Descriptive Research Design. Correlational Research Design. Experimental Research Design.
Why is a case study used in qualitative research?
Qualitative case study methodology enables researchers to conduct an in-depth exploration of intricate phenomena within some specific context.
What statistical analysis is used in case-control study?
Logistic regression modeling, in its various forms, has become by far the most frequently applied method for multivariable analysis of case-control studies.
What is the main strength of a case-control study?
What are the 7 types of research design?
Creating a research topic explains the type of research (experimental, survey research, correlational, semi-experimental, review) and its sub-type (experimental design, research problem, descriptive case-study).
What are 5 qualitative research designs?
Here are five common design approaches:
- Historical Study. A historical study is the ideal choice for studies that involve extensive examination of the past — including people, events and documents.
- Phenomenology. Phenomenology is a wide-ranging form of study.
- Grounded Theory.
- Ethnography.
- Case Study.
What are the 3 methods of case study?
He has helpfully characterised three main types of case study: intrinsic, instrumental and collective[8]. An intrinsic case study is typically undertaken to learn about a unique phenomenon. The researcher should define the uniqueness of the phenomenon, which distinguishes it from all others.
Is case study quantitative or qualitative?
qualitative data
Case studies tend to focus on qualitative data using methods such as interviews, observations, and analysis of primary and secondary sources (e.g. newspaper articles, photographs, official records). Sometimes a case study will also collect quantitative data.
Is a case-control study analytical or descriptive?
Analytical observational studies include case””control studies, cohort studies and some population (cross-sectional) studies. These studies all include matched groups of subjects and assess of associations between exposures and outcomes.
Is a case-control study experimental?
A randomised controlled trial is an experimental study. In contrast, case-control studies are observational studies. These are two different groups of studies.
What are the benefits of a case-control study?
What are the 4 types of research methodology?
Data may be grouped into four main types based on methods for collection: observational, experimental, simulation, and derived.
What are the 4 main types of research?
There are four main types of Quantitative research: Descriptive, Correlational, Causal-Comparative/Quasi-Experimental, and Experimental Research.
What are the 7 types of qualitative research?
