(Solution) Nr505 Week 3: Elements of Quantitative Research: Design and Sampling

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.

  • Select a single-study quantitative research study article related to your specialty track and provide the permalink to the article. Then discuss each of the following items.
  • 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).
  • 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?


The single quantitative study selected for this discussion is the Efficacy of HPV-based screening for prevention of invasive cervical cancer: follow-up of four European randomized controlled trials by Ronco et al. (2014). The permalink for this article is: https://www.sciencedirect.com/science/article/pii/S0140673613622187

This study used an experimental study design. According to Hancock and Algozzine (2016), the experimental study design is research that is conducted with a scientific approach, where a set of variables are kept constant while others being measures as the subject of the experiment. As such, taking this study into account, it employed randomized controlled trials with the aim of determining the efficacy of HPV-based screening for the prevention of invasive cervical cancer. In four randomized trials, HPV-based screening for cervical cancer…Please click the Paypal icon below to purchase full solution for only $5
