How are the specific questions of a research problem formulated?
A RQ can address different formats depending on the aspect to be evaluated. To develop a RQ, one needs to begin by identifying the subject of interest and then do preliminary research on that subject. The researcher then defines what still needs to be known in that particular subject and assesses the implied questions.
What type of study design should be used to investigate an exposure that is relatively uncommon?
Uncommon Outcome: If the outcome of interest is uncommon or rare, a case-control study would usually be best. Uncommon Exposure: When studying an uncommon exposure, the investigators need to enroll an adequate number of subjects who have that exposure. In this situation a cohort study is best.
What is exploratory research method?
Exploratory research is defined as a research used to investigate a problem which is not clearly defined. Such a research is usually carried out when the problem is at a preliminary stage. It is often referred to as grounded theory approach or interpretive research as it used to answer questions like what, why and how.
How do you formulate general problem and specific problem?
Consider 5 ways to formulate the research problem:
- Specify your research objectives;
- Review its context or environment;
- Explore its nature;
- Determine variable relationships;
- Anticipate the possible consequences of alternative approaches.
What is specific problem in research?
A research problem is a specific issue, difficulty, contradiction, or gap in knowledge that you will aim to address in your research. The type of research problem you choose depends on your broad topic of interest and the type of research you want to do. This article helps you identify and refine a research problem.
What is a specific research question?
A research question is a specific inquiry which the research seeks to provide a response to. It resides at the core of systematic investigation and it helps you to clearly define a path for the research process. A research question is usually the first step in any research project.
What type of research study approach is used when existing data are used and analyzed?
Secondary research is a common approach to a systematic investigation in which the researcher depends solely on existing data in the course of the research process. This research design involves organizing, collating and analyzing these data samples for valid research conclusions.
Which of the following study designs allows us to examine the multiple effects of one exposure?
Cohort studies form a suitable study design to assess associations between multiple exposures on the one hand and multiple outcomes on the other hand. They are especially appropriate to study rare exposures or exposures for which randomization is not possible for practical or ethical reasons.
What is an explanatory research question?
Explanatory questions (why is…). These questions are about explaining the causes for something. This requires that the relationship between different variables is studied.
What is an exploratory question?
Exploratory Questions: Similar to descriptive questions in quant research, this form of question looks to understand something— without influencing the results with preconceived notions. For example, asking how a product is used or perceptions around a certain topic are two types of exploratory questions.
