Sampling Strategy and Sample Size for a Quantitative Research Plan Introduction When a researcher is constructing a sampling method, the questions about the population where the sample will come from and the size of the sample to be used come into play for the purpose of seeking statistical validity (Frankfort-Nachmias & Nachmias, 2008). Parahoo (2014) explains that, in order for sampling method or strategy to be considered credible, defining the population to be sampled, type of sampling,…

obtain, as participants may easily be accessible and available (Frankfort-Nachmias & Nachmias, 2008). However, it may skew the sample, tainting it through introducing sampling bias. As a result, this strategy may not culminate in a representative sample of the population (Frankfort-Nachmias & Nachmias, 2008). Likewise, purposive sampling has the drawback of being based on the subjective judgment of a researcher to obtain a sample (Frankfort-Nachmias & Nachmias, 2008). Since it is impossible to…

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, n.d.). The authors cite that the sampling method used pose a limitation to the study. The study sample includes only nurses who were employed in the study hospital that chose to answer the CWEQ-II…

In the aspect of sampling, the scale was small, national that the place they conducted in Denmark and had 34.4 percent response rate (Jensen & Sørensen, 2013, p. 50). However, they managed to collect their data from the digital online survey, focus group interviews and covert…

Social Work Burnout and Its Effects on the Social Worker Name Institutional Affiliation Social Work Burnout and Its Effects on the Social Worker Introduction Social work burnout is has effects on the productivity of the worker; however, it is important to understand if and how the burnout affects a social worker. In the pursuit to understand the reality, there must be logical and empirical support (Babbie 2010, pg, 4). Like in epistemology, a science of knowing, which may rely on…

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…

ranked or ordered for example: binary (pass or fail, 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…

Measuring validity is important because it determines the impact of research. Validity is defined as “an integrated, evaluative judgment of the degree to which empirical evidence and theoretical rationales support the adequacy and appropriateness of inferences and actions based on test scores or other modes of assessment” (Salkind, 2010, p.1). There are many criteria of rigorous research, for example, internal validity, external validity, objectivity of observer, replicability, and reliability…

Notably, random sampling method was applied in the research. This ensures that error that result from bias are zero rated in the research. Moreover, random sampling is easy to apply as well as accurate in cases of large population under study, as was the case with music therapy. Overall, the selected sample represents 17 percent of entire…

Describe the sampling strategy. How appropriate were the various sampling design decisions? The sampling strategy is the first most important part of conducting this kind of research. According to Cooper and Schindler (2014) the most important characteristic of a sampling is to determine whether it represent the population it is supposed to represent. According to the article, “McMahon Group distributed mail surveys to 1,650 members and their spouses in January 1999” (Cooper & Schindler, NCRCC:…
