Ch. 5 Sampling p. 71-73

Respond to the topic below using the available reference: The sampling chapter will focus on data collection and deciding what variables to examine. A variety of sample options will be determined and assessed as to whether they accurately describe the population being examined. The degree to which they accurately portray the observed population will also be determined and discussed throughout this chapter. This chapter will also look over sample size, a couple methods of sampling, likelihood or non-likelihood of sampling and a plethora of determining sample selections (Faulkner & Faulkner, 2014). One objective of studies is to come to educated conclusions from the selected sampling about the overall population being sampled. “In research, a population is a set of entities from which a sample can be drawn either to describe a subsection of that population or to generalize information to the larger population” (Faulkner & Faulkner, 2014, p.71). In a population each member is referred to as elements. Studying an entire population is not possible, this is why samplings are conducted using elements from the population. Sampling is the most effective use of all resources (Faulkner & Faulkner, 2014). When researchers use samplings this is so they can hopefully discover more about the whole population. Observations are then made about elements chosen from the sample group. Inaccurate conclusions about the larger population can be made when people observe only one element out of a sample. In order to have more accuracy in studies, it is important to choose a variety of elements which will make up the sampling within the population being observed (Faulkner & Faulkner, 2014). Two important aspects of sampling are sampling frame and enumeration units. “A sampling frame is a list of all elements or other units containing the elements in a population. An enumeration unit contains one or more units to be listed in the sampling frame” (Faulkner & Faulkner, 2014, p. 72). Researchers can select various elements within a sample frame in order to glean more information as the study progresses. The sampling unit is a chosen unit of the population that is included in the sampling frame (Faulkner & Faulkner, 2014). Random selection and random assignment help to ensure the study maintains diversity in order to hopeful give an accurate portrayal of the observed population. In a large population elements are randomly selected to participate in the study, this is called random selection. A random assignment means the element is randomly given a particular placement in a study (Faulkner & Faulkner, 2014). “Representativeness is assumed when characteristics of the sample are similar to those of the population from which the sample was drawn” (Faulkner & Faulkner, 2014, p. 73). In order to maintain good representatives, it is important to have a big enough sample group. A technique commonly used to determine appropriate sample size is to list the number of variables in the study. After this has been done, they then select cases that match each variable. The authors of our book express that most researchers feel ten to twenty cases per variable are adequate in order to best represent a given population. Subject participation can be challenging for researchers due to having to include adequate representation for each variable (Faulkner & Faulkner, 2014). Even though I understood the reading, I did find it a little time consuming to fully grasp what the text was covering in these pages. I feel sampling is probably not that hard to understand but the text seemed to make it more difficult than necessary. I would imagine if we would have actually been setting in a class, this would have been covered relatively quickly. Reference Faulkner, S. S., & Faulkner, C. A. (2014).

This writer was very communicative and prompt. Handed in assignment before the deadline. However, the writer was unfamiliar with the field of my essay, so it didn't work out.
