RESEARCH METHODOLOGIES - EBP
Sample Solution
-
Quantitative research: Quantitative research is a research methodology that uses numbers and statistics to collect and analyze data. It is often used to test hypotheses and make predictions. Quantitative research is typically used in the natural sciences, but it is also used in the social sciences, such as psychology and sociology.
-
Qualitative research: Qualitative research is a research methodology that uses words and images to collect and analyze data. It is often used to understand people's experiences and perspectives. Qualitative research is typically used in the social sciences, but it is also used in the natural sciences, such as anthropology and ecology.

Mixed-method research: Mixed-method research is a research methodology that combines quantitative and qualitative research methods. It is often used to get a more complete understanding of a research problem. Mixed-method research is typically used in the social sciences, but it is also used in the natural sciences, such as health sciences.
Here is a table that summarizes the key differences between quantitative, qualitative, and mixed-method research methodologies:
| Feature | Quantitative research | Qualitative research | Mixed-method research |
|---|---|---|---|
| Data type | Numbers and statistics | Words and images | Numbers, statistics, and words and images |
| Purpose | To test hypotheses and make predictions | To understand people's experiences and perspectives | To get a more complete understanding of a research problem |
| Strengths | Provides objective and generalizable findings | Provides in-depth and rich insights | Can provide the best of both quantitative and qualitative research |
| Weaknesses | Can be limited in its ability to understand people's experiences | Can be time-consuming and difficult to analyze | Can be difficult to combine the two methods effectively |
The relationship between peer-reviewed articles and clinical issues is that peer-reviewed articles are often used to inform clinical practice. Researchers conduct studies to investigate clinical issues and publish their findings in peer-reviewed articles. These articles are then read by healthcare professionals, who can use the findings to improve their practice.
Research ethics is a set of principles that guide the conduct of research. These principles are designed to protect the rights and welfare of research participants. Research ethics is particularly important in clinical research, where the participants are often vulnerable.
The aims of research studies presented in peer-reviewed articles vary depending on the type of research. However, some common aims include:
- To test a hypothesis
- To describe a phenomenon
- To understand a process
- To develop a new intervention
- To evaluate an existing intervention
The research methodologies described in peer-reviewed articles also vary depending on the type of research. However, some common research methodologies include:
- Randomized controlled trials
- Cohort studies
- Case-control studies
- Qualitative studies
- Mixed-method studies
The strengths, reliability, and validity of research methodologies are important considerations when evaluating research findings. Strength refers to the ability of a research method to produce accurate results. Reliability refers to the consistency of the results produced by a research method. Validity refers to the extent to which a research method measures what it is supposed to measure.
The best research methodology for a particular study will depend on the research question, the type of data that is being collected, and the resources that are available.
