NR 439 Week 3 Discussion, Research Problems, Designs, and Sample

NR 439 Week 3 Discussion, Research Problems, Designs, and Sample 1. After you review the designs, describe which research design you would expect to find when searching for evidence relevant to your own research question from Week 2. Why? Explain your answer. After review, I believe that the most common research design would be the Quasi-Experimental Design. According to our text, treatment is introduced to the group but there aren’t random assignments or a control group. I think that with CAUTI’s the best way to determine improvement rates is to utilize a policy that targets all patients with foley catheters and then compares the number of infections to the previously recorded infection rate. This type of design cannot definitively determine causality and the research can be weaker than experimental design. But I believe this would be the greatest benefit to my research question. Since choosing to treat patients differently could potentially cause harm to my patients. 2. The most common sampling method is the convenience sample; therefore, many of the studies that you find for evidence use this sampling method. What are the implications for using a convenience sample on the way you interpret and use the findings? “Convenience sampling (also known as availability sampling) is a specific type of non-probability sampling method that relies on data collection from population members who are conveniently available to participate in study,” (Research Methodology Website, n.d., para. 1). A convenience sample has several advantages. These include: a.) Simplicity of sampling b.) Helpful for hypothesis generation c.) Short-time frame for data collection d.) Cheapest to implement The disadvantages of convenience sampling include bias of sampling and a high level of sampling error. This type of sampling is both beneficial for initial information and data collection, but it could also skew your results because it doesn’t give an accurate account of the entire population (Research Methodology Website, n.d.).
