Nonprobability sampling

Throughout scientific studies, researchers utilize sampling and conduct research that identifies probability and nonprobability, reliability, and validity of research. Also, scientists utilize telephone surveys, online surveys, focus groups, and surveys via websites when collecting data for research and need to be aware of the advantages and disadvantages of each of them. Sampling is the process of selecting a small part of a population for inspection and utilizing that smaller part of information to represent a larger population. It may be impossible for scientists to determine the characteristics of a vast population; therefore, the purpose and fundaments of sampling is to help scientists examine the characteristics of a larger population in a smaller way. Because information is taken from cautiously drawn samples within a smaller group, another fundament of sampling is receiving results that are more accurate than they would be from a larger group (Monette, Sullivan, & DeJong, 2011, p.135). Two methods used in research are probability and nonprobability sampling. Probability sampling such as simple random sampling (SRS), guarantees that all scientific components have an equal chance of being included in the sample (Monette et al., 2011, p.139). For example,…

include the following. The study is based on Experimental design. The investigators seek to test the efficiency of nursing interventions. Groove, Burns & Gray (2013) state: The three essential elements of experimental research are (1) randomization; (2) researcher-controlled manipulation of the independent variable; and (3) researcher control of the experimental situation, including a control or comparison group. Groove et al. 10381-10382 (2013). This study incorporates those three criteria.…

more accurate our final results will be. Since our main sampling method uses the convenience approach, the majority of our sample will be UFV students. Our working population, the UFV students, represent the multicultural aspect of our target population well. UFV has a variety of students from different cultural backgrounds; therefore, they will have different ingrained values and attitudes towards EF products. However, due to the mean age of students are likely lies on the younger side, this…

The goal of lesson three was to identify the sampling methods in five psychology research publications and discuss any ethical considerations posed in these articles. This, appropriateness of the sampling methods used, and artifacts and confounding variables introduced because of the techniques are discussed. In addition, a review of whether the researchers accomplished their goals by utilizing these processes follows. McCann & Holmes’s used nonprobability convenience sampling for their study,…

sample. To generalize from the sample to the population, the sample has to be representative of the population. The safest way to ensure that it is representative is to use a random selection procedure. You can also use a stratified random sampling procedure, to make sure that you have proportional representation of population subgroups” (Hopkins, 2000). The flowing is the type that I will fit my research…

Population (2.5 points): The population in this study is nursing professionals. Research study design (2.5 points): This study is a nonexperimental design. In a nonexperimental design, the independent variable is not manipulated, it explores relationships between variables, and there is no controlled group. Independent variable (2.5 points): The independent variable in this article is the palliative care knowledge test (PCKT). Dependent variable (2.5 points): The dependent variable is to…

survey responses of 80 other country clubs. According to Cooper and Schindler (2014), sampling is examination of attributes of a collection and is considered quality if the attributes accurately represent the population depicted. Furthermore, the authors state a sample must consider the target population, parameters of interest, sampling frame (list of elements), sampling method (probability or nonprobability), and necessary sample size (pp. 344-348). Apparently, McMahon Group’s sampling method…

“A convenience sample of 259 nurses was obtained from all active-status, registered nurses employed at the study hospital” (Donahue, et al., 2008, p. 3). Some advantages of convenience sample are sample availability, accessibility, requires little time and effort, and cost effectiveness for the researchers, thus, the word convenience. However, sampling method suffers from a major disadvantage that relates to inaccurate representation of the population, which can distort results (Wisegeek,…

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…

more than five years of experience in practice. The experience levels selected for this study were based on Benner’s Novice to Expert framework that recommends a nurse is “competent” after two to three years of practice and becomes an “expert” when they recognize what is required in a given situation built on solely their intuition and experience (Benner, 1982). To allow for the potential transferability to similar units across the nation in large academic medical centers, additional…
