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 6 and 7)
as well as your 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.
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 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 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.

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 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?
