Research Design, Strengths And Limitations, And Rationale

Research designs and methods are not created equal. Each design and method has its strengths and limitations. True experimental research designs, for example, tend to have higher levels of validity compared to ex post facto designs. Once you decide on your research design this week and the method, which you will cover in Week 8, it is important to evaluate limitations of each and consider how you will attempt to prevent or minimize them in your study.

Either determining research questions or the research design might come first; most likely, you will circle back from one to the other until they are aligned and one flows logically from the other. It is necessary to have both in place before deciding on your methodology.

To prepare for this Assignment, review the Learning Resources for the week. Your research design represents the structure of your study. In other words, the research design includes (a) elements of treatment; and (b) the number, type, relationship, and strategies to control the variables you are studying.  It also includes (c) the number and type of individuals or groups in your sample.  Finally, the research design includes (d) the measurements; (e) sampling methods; (f) data collection time frame; and (g) setting (Walden University2010).  Research methods are used to carry out research designs; methods fall under two broad categories: (a) Quantitative (e.g., experimsental, quasi-experimental) and (b) qualitative (e.g., case study, grounded theory, ethnography) (Trochim & Land, 1982). More on that in Week 8.

Again, your problem statement and research questions will help you determine your research design, and your research design will help determine your research method.  In this Assignment, you will select a research design and examine its appropriateness for your potential research.

In your Discussion assignment, you have posted at least two research questions. In the Week 7 Assignment, using the required readings and media resources on research design, write 4-5 pages (a) describing at least one potential research design you could use, (b) the strengths and limitations (including reliability and validity issues) of that design selection, and (c) the rationale for your selection: Finally, explain how your problem statement, purpose statement, and research questions align with your proposed methodology and design. Be specific.

Attached is my proposed topic plus draft outline of what you can use to complete the assignment.

**Here is my research questions


Dissertation Topic:

African American Male Juvenile Rehabilitation versus Incarceration Punishment.

Problem Statement:

African American male juveniles face brutal punishment that includes spending a long time in correctional services. To help prevent the offenders reoffending, it is critical to introduce rehabilitative programs among the offenders than providing direct punishment.


The research aims at identifying the difference that exists between juvenile rehabilitation and incarceration punishment among African-American offenders. When the individuals are released back into society from incarceration punishment, most of them get involved in other criminal activities.

Research Questions:

1. What youth programs focus on deterring criminal behaviors of juvenile offenders?

2. What was the recidivism rate for juveniles that faced immediate punishment, compared to those that received delayed punishment?

3. What are the risk levels on recidivism with juvenile offenders? Which juveniles risk levels are more likely to recidivism?
