Sampling

Building on this research, one could vary the data by including more high school students from different backgrounds and socioeconomic statuses. Finding out how these factors contribute to the number of AP classes taken and cumulative GPA will increase the effectiveness of this observational study. The limitation of the research was that many of the students who took the survey were from Ms. Moneypenny’s AP Statistics class, and other AP classes, as listed in the Introduction. This gave the data…

Yes/No); nominal (gender, race); ordinal (age group) and quantitative-discrete (number of medication errors) or continuous (amount of time-time to balloon, ED waiting time). Measure phase might make a use sampling for data collection (simple random sampling, cluster sampling, stratified sampling). Sigma Six uses following formula to decide on the sample size (n) for continuous data: n= (1.96ϭ/∆) ^2, and n= (1.96ϭ/∆) ^2*P (1-P) for discrete data. Where P is the estimated percentage of the…

A Quantitative Research Design Critique The research problem that I have selected in Unit 1 is pressure ulcers. There have been research and studies conducted in order to shed light on this problem. There are research studies that aim to prevent pressure ulcers from happening by implementing interventions. Aside from that, as healthcare professionals, we have to determine the validity of the study. This paper aims to review the research conducted by Bergstrom et al. (2013) in determining the…

The population used in this journal article is clearly described and involved the recruitment of registered nurses from a large academic medical center. Differences in fatigue levels have been demonstrated based on the RN’s years of experience (Barker and Nussbaum, 2011b). Nurses with more work experience may have a distinctive outlook and perspective on coping with fatigue versus a nurse with limited experience. Thus, RNs who were recruited involved nurses with less than two years of experience…

Studies and information gathered from the population offers a valuable tool for a marketing manager to utilize when one is trying to increase wine sales in an operating establishment. Many studies exist, which concern factors shown to influence dining satisfaction such as the quality of food, the quality of the service, as well as the environment and ambiance. However, nominal research exists, which focuses on the customer’s satisfaction with wine when they are in a restaurant atmosphere, while…

researchers to obtain detailed and rich data.5 As such, this may affect the credibility of the findings. The participants were selected first through a formal support group by using purposive convenience sampling with no incentives. Offredy and Vickers reported that this method is a weak sampling technique; however, it is one of the most commonly…

40 or higher on the scale is required to required to meet the SED criteria. The sampling method used was non-probability sampling, in which every element has an unknown and usually different chance of selection. Non-probability sampling is not representative of the population, no generalizations can be made, only speculations that what hold true for the sample also does for the population. Non-probability sampling was appropriate for the research question because they were not randomly…

Finally, the data collection and sampling approach may have a potential flaw. These settings should provide enough interview respondents for almost every stratified category identified earlier except for instructors of mariachi. It is not hard to imagine that some of the various mariachi musical performers may be instructors as well, so there may be overlap within these two subgroups of cultural creators. There is also a chance that mariachi performers, aficionados, and gatekeepers may…
