By research design:

• Experimental research: Experimental research is used to test causal relationships between variables. In an experimental study, researchers randomly assign participants to different groups and then manipulate one variable while keeping all other variables constant. They then compare the outcomes of the different groups to see if the manipulated variable had an effect.
• Quasi-experimental research: Quasi-experimental research is similar to experimental research, but it does not involve random assignment of participants to groups. This type of research is often used in situations where it is not feasible or ethical to randomly assign participants, such as when studying vulnerable populations.
• Non-experimental research: Non-experimental research does not involve manipulating variables or testing causal relationships. This type of research is often used to describe phenomena, to identify relationships between variables, and to explore new areas of inquiry.

By research purpose:

• Descriptive research: Descriptive research is used to describe a phenomenon in detail. This type of research is often used to identify the characteristics of a population or to measure the prevalence of a phenomenon.
• Correlational research: Correlational research is used to identify relationships between variables. This type of research does not test causal relationships, but it can be used to generate hypotheses about which variables may cause changes in other variables.
• Explanatory research: Explanatory research is used to test hypotheses about causal relationships between variables. This type of research is often used to develop theories about how phenomena work.
• Exploratory research: Exploratory research is used to explore new areas of inquiry and to generate new ideas. This type of research is often used to identify research questions and to develop hypotheses for future research.

By research setting:

• Laboratory research: Laboratory research is conducted in a controlled setting, such as a research lab or a simulated environment. This type of research is often used to test hypotheses about causal relationships between variables.
• Clinical research: Clinical research is conducted in a healthcare setting, such as a hospital or a clinic. This type of research is often used to test the effectiveness of new treatments and interventions.
• Community research: Community research is conducted in the community, such as in people’s homes or in public places. This type of research is often used to study the health and well-being of populations and to identify factors that influence health.

This is just a brief overview of the different ways that nursing research methodologies can be classified. There are many other ways to classify nursing research methodologies, and the specific classification that is used will depend on the nature of the research question being investigated.
