PhD quantitative studies

Instructions
Create a brief summary of the research method, and then design your plan to use to investigate your research topic.
Select a method and design appropriate for a PhD study. PhD quantitative studies must demonstrate both internal and external validity (e.g., large, random samples, statistical power and representativeness). Qualitative studies must demonstrate validity within the context of the specific qualitative design (e.g., credibility, dependability, transferability, trustworthiness). Replication studies are not permitted. Your summary must address the following:
1. Note a specific method and design you plan to use in your research.
2. Describe and substantiate the appropriateness of the method and design to respond to the stated problem, purpose, and research questions.
3. Note how the proposed method and design accomplish the study goals, why the design is the optimum choice for the proposed research, and how the method aligns with the purpose and research questions.
4. Provide appropriate foundational research method support for the proposed study design.
5. Explain the particular data gathering techniques and data analyses processes. Sample size of the study population should be identified and must be appropriate and justified based on the nature of the study design. Quantitative analyses must include justified sample size determination.
Length: 2-3 pages, not including title and reference pages
Your assignment should demonstrate thoughtful consideration of the ideas and concepts presented in the course by providing new thoughts and insights relating directly to this topic. Your response should reflect scholarly writing and current APA standards.

When a new study is undertaken, the researcher has many options to consider when selecting a valid research method. Quantitative research allows researchers to gather and manipulate numerical data to answer research questions. Qualitative research requires the analysis of non-numeric data such as narratives or interviews. Research questions define the study’s purpose and closely guide the researcher toward the optimal design for his or her investigation. Once a decision has been made whether a qualitative or quantitative study best fits the desired model for the research, the researcher must decide the type of qualitative or quantitative designs to employ. It is helpful to survey the wide variety of design options available to researchers.
Here are some of the different choices available:
Qualitative Research Designs Quantitative Research Designs
Case Study Descriptive
Phenomenology Quasi-experimental
Ethnography Correlation
Grounded Theory Experimental
Here are some of the differences in terminology when describing quantitative and qualitative research validity:
