NR 505 Week 3: Elements of Quantitative Research: Design and Sampling Discussion
NR 505 Week 3: Elements of Quantitative Research: Design and Sampling Discussion – The focus of the Week 3 discussion is on two important elements of quantitative research studies- design and sampling. The approach or design, quantitative or qualitative, also applies to EBP projects. Both quantitative and qualitative have different designs or traditions that fall under these two broad categories.

- Identify whether the research study design is experimental, quasiexperimental, or nonexperimental. Provide the rationale for your answer.
- Identify the appropriate representation for the research study article you selected using the nomenclature of X for intervention, O for observation and data collection, and R for random a assignment to a research study group.
- Identify the type of sampling (probability vs. nonprobability) that was used in the research study article you selected.
- Identify one advantage and one disadvantage to the sampling type used (probability vs. nonprobability). NR 505 Elements of Quantitative Research: Design and Sampling Discussion.
- Identify whether there was random assignment to research study groups in the research study article you have selected.
- If random assignment to groups was used, how does this strengthen the research study design?
NR 505 Week 3: Elements of Quantitative Research: Design and Sampling Discussion SAMPLE
I chose a qualitative research study that looked at primary care physicians and how they screen for military service and post-traumatic stress disorder (PTSD). This study is pertinent to my PICo question, are post war veterans at a higher risk for suicide as they re-integrate into society? As a future nurse practitioner (NP), I see a correlation with health care providers understanding if their patients have served in the military and if they may be experiencing physical or mental symptoms that are adversely affecting their well-being as a way of reducing suicide risk among veterans. Mohler & Sankey-Deemer (2017), NR 505 Elements of Quantitative Research: Design and Sampling Discussion. discuss the link between PTSD and veteran suicide and how veteran suicide has been on the rise in the last ten years. Due to challenges with distance and access to a veteran health facility, Mohler (2017), discusses the importance of primary care physicians screening the patients for military service and any health concerns they may be experiencing as a result of time served.
Research study design: Non- Experimental
This study falls within the parameters of non-experimental because an intervention is not introduced, and the researchers are simply collecting data from primary care physicians. Polit & Beck (2017), discuss the researcher role in non-experimental study as simply being bystanders without introducing any treatments that could affect the data.
Representation for the research study: O
Type of sampling: Nonprobability
My rationale for choosing this sample style was simply by the wording of the sample description within the article. According to Mohler (2017), primary care physicians were located using online search engines, Facebook, provider directories, and professional directories and a comprehensive list of all primary care physicians within the chosen demographic area was not done.

Rural primary care physicians were likely to have been excluded due to likelihood of being active and present on modern internet websites and search engines. Polit (2017), describes nonprobability as a sampling method in which every element does not have a chance to be included. An advantage to this sample method would be the ease in locating primary care physicians to participate and have a large sample of participants with which to work with. The disadvantage would be the likely hood of excluding rural primary care physicians when research has shown veterans in rural communities have a higher risk of suicide.

Random assignment: No random assignment was utilized.
According to Polit (2017), random assignment is used when assigning participants to treatment conditions or interventions. Because this was a non-experimental research design, no interventions were utilized and therefore no random assignment applied.
