I believed that posted the assignment in the discussion board but forgot to list it under the assignments tab.I apologize for the confusion.Please review the next line below for clarification.
Chapter 6: Descriptive research design, mixed methods and meta-analysis & Chapter 7: Epidemiology and Longitudinal Studies
Read Chapter 6 & 7
Discussion # 3
June 6, 2020
Based on your course reading assignments (Chapters 6and 7)
as well asyour pending research problem, what type of study do you believe you are conducting,? and please explain why?
post should be no greater than 250 words, the equivalent of of three (3) paragraphs, 4-5 lines each.
Week Five
Moving into Week 5, we are going to look at a little more sophisticated methods as they relate to research.
Descriptive research design, mixed methods, and meta-analysis highlighted in Chapter 6. Also, we will review Epidemiology and Longitudinal Studies covered in Chapter 7.
Take a moment to review the listed publications and videos below to help bring clarity and supplement your course readings as you progress through our course.
Descriptive Research
Descriptive research is a study designed to depict the participants in an accurate way. More simply put, descriptive analysis is all about describing people who take part in the survey.
There are three ways a researcher can go about doing a descriptive research project, and they are:
- Observational, defined as a method of viewing and recording the participants
- Case study, defined as an in-depth study of an individual or group of individuals
- Survey, defined as a brief interview or discussion with an individual about a specific topic

Mixed Methods Research
Mixed methods research (Extracted from the article below) is the use of quantitative and qualitative methods in a single study or series of studies. It is a new methodology that is increasingly used by health researchers, especially within health services research. There is a growing literature on the theory, design, and critical appraisal of mixed methods research. However, few papers summarize this methodological approach for health practitioners who wish to conduct or critically engage with mixed methods studies.

Meta-Analysis
Meta–analysis is a statistical technique for combining data from multiple studies on a particular topic. A Meta-analysis is an analytical tool for estimating the mean and variance of underlying population effects from a collection of empirical studies addressing ostensibly the same research question. Meta‐analysis has become an increasingly popular and valuable tool in psychological research, and significant review articles typically employ these methods.

Epidemiology
According to the Centers for Disease Control, Epidemiology is the method used to find the causes of health outcomes and diseases in populations. In epidemiology, the patient is the community and individuals are viewed collectively. By definition, epidemiology is the study (scientific, systematic, and data-driven) of the distribution (frequency, pattern) and determinants (causes, risk factors) of health-related states and events (not just diseases) in specified populations (neighborhood, school, city, state, country, global).

Longitudinal Studies
Longitudinal Study, an epidemiologic study that follows a population forward over time, evaluating the effects of one or more variables on a process. If individuals are followed, it is termed a longitudinal cohort study. If classes—e.g., age classes—are studied, it is a longitudinal cross-sectional study. Longitudinal studies are the converse (opposite) of horizontal (parallel) studies.

This week we will have a discussion question that is due. Remember, your initiation post is due by Wednesday and two follow up responses are due by Saturday night. Please refer to your course syllabus for the grading rubric that is required.
Discussion Question – Week Five
Based on your course reading assignments and your pending research problem, what type of study do you believe you are conducting, and please explain why?
Expert Solution Preview
Based on the course reading assignments in Chapters 6 and 7, as well as the pending research problem, the type of study that I believe I am conducting is a mixed methods research study.
Mixed methods research involves the use of both quantitative and qualitative methods in a single study or series of studies. This approach allows for a more comprehensive and in-depth understanding of the research problem by combining the strengths of both quantitative and qualitative data. In my research, I will be collecting both numerical data and qualitative data to gain a more holistic perspective on the topic.
The use of mixed methods research is suitable for my research problem because it will enable me to explore the underlying phenomena and factors related to the research problem in a more nuanced way. It will allow me to generate both statistical evidence and rich narratives that can provide a deeper understanding of the topic. Additionally, the use of mixed methods research will allow me to triangulate the findings, enhancing the validity and reliability of the study.
In summary, based on the course readings and the pending research problem, I believe that I am conducting a mixed methods research study. This approach will enable me to gather comprehensive and diverse data to address the research problem effectively.
