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,…

History Sampling is regarded as one of the most necessary parts of auditing today, but as a matter of fact, it was not until 1997 that the “Audit Sampling” standard was issued by the International Auditing and Assurance Standards Board (IAASB). When auditing first came into fruition sampling was not given the same consideration that is has today, as company owners were “interested in discovering major accounts of fraud or misstatements in the financial statements” (Oana, Tatiana 2013, and…

Describe the sampling method used in this study The primary objective of conducting research is the ability to come to a conclusion in regard to the entire population from results obtained through sampling. The sampling method used in this study is the simple random sampling. The random sampling method is a sampling procedure that ensures each element in the population will have an equal chance of being included (Zikmund, Babin, Carr, & Griffin, 2013, p. 396). Random sampling is a beneficial…

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:…

According to Melnyk and Overholt (2015), sampling involves choices about study sites and people who will be able to provide data and perceptions about the study topic. There are different approaches to sampling that are based on a combination of criteria. When planning a research, nurses must make sure that the decisions that are being made are ethical. In my clinical practice, research is important. The most important aspect of the research that we have seen is informed consent. The…

5. Explain any sampling bias? Answer – The surveys were conducted by the people who were in attendance of the shows at the VSO that were taking place. Due to this the views that are expressed are of people who are in attendance, and are not of people who are not coming to the VSO or of the people who have unsubscribed or who have had a negative experience there. Hence there may be a bias with the responses being positively skewed as they are from the people who have gone to the orchestra at…

The one types of non-probability sampling methods is convenience sampling. Convenience sampling occurs when data collection is obtained from the easiest to get hold of subjects. For example, if you were going to do a study on hospital-provided water births in Oregon, and you were looking to find out what percentage actually end up delivering in water, opposed to abandoning the water prior to delivery. In a convenience sampling, I would only take information for my local hospital because it is…

In the quantitative article Ozdamli and Uzunboylu used the stratified random sampling method. The teacher sample was made up of 25% of the total number. The student sample was made up of 9% of the target population. The qualitative authors decided to use the criterion sampling strategy. The teachers that were selected had to meet the criterion of using MCDs or taught students that uses MCDs such as, cell phones, smart phones, or tablet computer for teaching or learning. The quantitative…

In addition, the quadrat sampling is simple and with the table and the performance curve we were able to find the density and the area. The data can be analyze in with the curve or with the table. Both of the information provided in the curve and the table shows that 3 is the density of pill bugs in the area. The second method for estimating abundance is the mark recapture method. When performing this method the average population estimate is 190.211 beans. The standard error is 5.15812 and…

This type of sampling works best when trying to look at one particular issue, and then attempting to compare two or more groups. This technique offers a higher change of the study being statistically correct. This method requires dividing the population into groups, and then randomly selecting the final subjects from the different social stratification (Survey Sampling Methods, 2016). This study would have to be conducted with children ages 9 to 13, who have parents with narcissistic disorder or…
