University of Phoenix Wk 7 Quantitative Research Discussion Response

Question 1 Student Response:

Quantitative research is numerical data and Qualitative research is narrative data. “Correlational research: The researcher is interested in determining the relationship between two or more quantifiable variables. It is important to note that correlation does not determine cause and-effect.


research: The researcher randomly assigns participants to experimental and control groups and manipulates one or more variables to determine cause-and-effect. Ex post facto (or causal comparative): The objective of this design is to identify causal relationships among variables that cannot be manipulated such as gender, ethnicity, or birth order. Causal research can be used to determine cause-and- effect between variables. Action research: The researcher works collaboratively with an organization or institution to address a problem or create policy. There are various types of action research; each differs regarding the researcher’s role and the objectives. Appreciative inquiry: Like action research, but rather than focusing on existing problems it focuses on building on the existing positive aspects of an organization and envisioning innovative enhancements for the future. Case study: The researcher examines an existing bounded “case” such as an organizational or institutional process using multiple sources of data to triangulate knowledge about the case. Case studies require an explicit “type. Once the student selects a dissertation topic and identifies a problem, the student should develop a research purpose that aligns with the problem then select a research method and design aligned with the purpose. Note that alignment between the purpose and design is an iterative process; the purpose should be modified to reflect the selected design. The following information describes the three research methods. The most used method within practitioner doctoral programs is qualitative followed by quantitative. The third method, mixed method, combines qualitative and quantitative approaches.” (Phoenix, 2021)

Question 2 Student Response:

I think that picking an applied research designs all depends on the type of research that you are doing for the research plan of the dissertation. “A well-planned research design helps ensure that your methods match your research aims and that you use the right kind of analysis for your data. You might have to write up a research design as a standalone assignment, or it might be part of a larger

research proposal

or other project. In either case, you should carefully consider which methods are most appropriate and feasible for answering your question. There are many ways you could go about answering this question. Your research design choices should be driven by your aims and priorities—start by thinking carefully about what you want to achieve. It’s also possible to use a mixed-methods design that integrates aspects of both approaches. By combining qualitative and quantitative insights, you can gain a more complete picture of the problem you’re studying and strengthen the credibility of your conclusions. As well as scientific considerations, you need to think practically when designing your research. If your research involves people or animals, you also need to consider

research ethics

. Quantitative designs can be split into four main types. Experimental and


designs allow you to test cause-and-effect relationships, while




designs allow you to measure variables and describe relationships between them.” (McCombes, 2021)Works Cited
