¶ … population (or data) you plan to sample for your study. There are a variety of sampling methods from which to choose. Your choice of sampling method will depend on your research design and method. For instance, if you are using a qualitative method you might use purposive or snowball sampling. If you are using a quantitative method, you might use simple random sampling or systematic random sampling. Like research methods, sampling methods each have specific strengths and limitations in terms of reliability and validity. There are also ethical considerations when using sampling methods with certain populations such as children, the elderly, the developmentally disabled, and individuals who are institutionalized.
Write a brief description of the population or type of data you plan to sample for your dissertation. Then describe the sampling method you plan to use and explain why you plan to use it. Finally, describe at least two issues (e.g., reliability, validity, and/or ethical issues) that might arise when using the sampling method and explain how you would prevent and/or minimize each. Be specific.

As stated in earlier documents in regards to this topic, the overall objective of this research is to determine the interventions which can minimize the hazards of negative outcomes for youths at-risk. The study depends...
Since much of the research conducted is going to be highly exploratory, it's important to get the most relevant sample of participants possible. Thus, if the researchers realize mid-way through the study that other tactics and tools should be used to gather data or otherwise adjust the plan, they will still have a compilation of the most relevant individuals for the purpose of the study.
Given the purposes of this study and the overall goals of the research, a purposive sampling method would be ideal. A purposive sample…is one that is selected based on the knowledge of a population and the purpose of the study. The subjects are selected because of some characteristic" (Crossman, 2014). As a result of the fact that this research is primarily concerned with specific cases of behavior and actions within specific communities that are considered outside of the norm, as inner city neighborhoods and families are being closely examined. Thus, because smaller minorities of people are being examined, researchers will be able to gain a more marked sense of the dynamics which influence them. Thus, a purposive sampling method will allow research select the families and individuals that are most desirable to find out…
Using a random sampling helps to insure that there will be a randomly equal number of learning disabled students, gifted students, underachievers and overachievers in each group. In addition the random sampling will help insure a statistically close to equal sampling of males and females in each group. Assumptions will also be made that the students will put forth their best effort in the class work and instruction so that the
By assigning the numerical value to all data, researcher is able to present data in tables, graph and chart to assist the presentation of the research findings. In addition, the data presented are used to compare the performances of the experimental group and control group. The graph, chart, and table are also used to make comparison of the two groups. Curricular Innovation Development The findings of the research seek to improve
This reduces response bias for better reliability of the information gathered and a higher anticipated response rate for an adequate sample size. A one month time frame gives better assurance of an appropriate response rate adequate analysis of results.

Export Business Plan: Moldovan Cellular Phones Purpose-Why has the plan been written? The plan has been written in order to guide our mobile phone export business. Cell phones in Moldova are rapidly overtaking land phones as many cellular phones now provide Internet access and cell phone computers. SMS, MMS and broadband are becoming standard features on cell phones. Nonetheless, mobile phones are expensive in Moldova and not everyone can afford them. Furthermore,
Nursing Research Analyzing Qualitative Data Qualitative data, which usually consists of narrative materials (Polit & Beck, 2008, p. 507), is analyzed by three major styles. Template analysis involves development of a guide to which gathered data is applied and adjustment of the guide as more data is applied. This method tends to be interpretive rather than statistical. Editing analysis involves interpretation of data for "meaningful segments," then development of a category scheme
446). Again, since data collection methods are relevant to specific research studies based on their questions, hypotheses, and literature reviews, this funneling of "phenomena of interest" should ideally suit most research studies -- so long as the those methods are tailored to meet a particular study. When researchers have narrowed down certain characteristics or behaviors that they are looking to observe in their study, they can do with a
