Sampling is the framework on which any form of research is carried out. A suitable sample that meets the inclusion and exclusion criteria of a research design must be chosen from a given population to carry out studies. In this essay comparison is made between stratified random sampling and convenience sampling. The population on which the researcher is interested in carrying out his or her research may be too large, therefore a suitable sample which can represent the population in correct proportion must be chosen. Restraints such as limitation of time, resources and many other factors necessitate the selection of a sample for research purpose so that better quality data is obtained from it and that the researcher can make statement about the population he or she is interested in (French,S et al.,2001,).The method of sampling should be cost effective, less time consuming and be simple in design to attract participants but care should be taken that accurate and valid data can be collected. The sample on which the study is actually done is derived from the population which is accessible to the researcher; the study sample may include all of the accessible population or a fraction of it and this accessible population is a part of the target population. The target population is the collection of cases to which generalization can be made and on which the researcher is ultimately interested in (Sim,J and Wright,C. 2000). Hence the entire process of collection of samples for the indented study can be termed as sampling. Sampling is broadly divided into probability sampling; in which the selection of samples are done at random and non- probability sampling; where selection of samples is entirely dependent on the researcher’s choice and ...

Two sampling methods include mail surveys and convenience sampling, a variation of a nonprobability sample. Mail surveys, inexpensive way to contact individuals over a large geographical area, provide anonymity to the respondent, and eliminate interview bias. Convenience sampling, a nonprobability sample, the only criteria is the convenience of the unit to the researcher, fast and uncomplicated, but the sampling error not determined.

Research is a systematic process that ultimately leads to the development of new knowledge and solutions to problems or questions (Adams, 2012). Evidence-based practice is the use of the best scientific evidence available to support clinical decisions when caring for individuals or groups of patients (Santos, Pimenta, & Nobre, 2007). The connection between research and evidence-based practice is derived from the fact that nurses use solutions found in research to validate and refine existing nursing knowledge. As a result, nursing practice is impacted. (Adams, 2012). In addition, the goal for conducting nursing research is not only to improve patient outcomes, but also to provide credibility to the nursing profession through evidence-based practice (Adams, 2012). Therefore, research provides the foundation for the develo...

For nursing, research has played a major role in the way clinical practice is done. Research has allowed nurses to provide appropriate care to patients. It allows them to perform their job by providing them the tools and information they need in order to make the decisions on the concerns for caring the patient (Polit & Beck, 2006). Moreover, research can also take focus on the workers themselves in order to improve the practice both on a professional and personal level. An example of a study conducted by King, Vidourek, and Schweibert of University of Cincinnati created a study to determine if there is a correlation between ...

741). Quantitative research can be experimental or nonexperimental in nature and identified according to the purpose of the study to include categories of: clinical trials, evaluation research, health services and outcomes research and survey research (Polit and Beck, 2017). The general flow of a quantitative research study involves five phases including conceptual, design and planning, empirical, analytic and dissemination (Polit and Beck, 2017, p. 55). This nursing research was conducted utilizing survey research as a self-administered questionnaire was utilized to obtain data from nurses (Kirwan, et al., 2013, p. 255). This was an appropriate quantitative research methodology fitting for this research study as it provided information relevant to the research
The sampling design process includes five steps which are closely related and are important to all aspect of the marketing research project. The five steps are: defining the target population; determining the sample frame; selecting a sampling technique; determining the sample size; and executing the sampling process.
