  • 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,…

  • Random Sampling Methods

    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…

  • Sampling Design Case Study

    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:…

  • Ethical Sampling Proposal

    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…

  • Non Probability Sampling Methods

    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…

  • Ozdamli And Uzunboylu: Stratified Random Sampling Method

    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…

  • Quadrat Sampling

    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…

  • Disadvantages Of Phone Surveys

    is recommended that researchers identify the methods they used to obtain that sample (Creswell, 2014). Creswell (2014) identified two methods for this process. First, he recommended selecting a random sample (Creswell, 2014). The central characteristic of a random sample is that all individuals have a non-zero and independent chance of being selected to participate (Chamberlain, 2016). Furthermore, randomization allows researchers to better generalize about a population (Creswell, 2016).…
