Research is a process of inquiry. In research study sampling theory is necessary, because it is a section of statistics, which included population, target population, sampling eligibility criteria, methods, plan, assessable population, elements, representatives. The sampling theory is not complete with selection of observation of population. That will start with the random sample, the use of probability theory with population limitations Then evaluate the data from the random sample and develop conclusions from the investigation. (course-note.org, n.d) There are two types of sampling approaches: Probability sampling approaches and non- probability sampling approaches. In probability sampling methods, each participant has same probability of being selected but, in non-probability sampling method, selected individual does not equal to the another individual. (fao.org, n.d)
For example, if a researcher want to do a study about the effectiveness of an educational program on medication compliance in people with diabetes, the researcher would like to be able to conclude that what he found in his …show more content…
Same as in research, once researchers gather enough information to support a hypothesis, they can develop a foundation to predict the result in similar situations with a certain degree of accuracy. There are two aspects of generalizability. Generalizing to a population and generalizing to a theory. In nursing research, for generalizability, nurses need a study sample and signify some population of interest also need to understand the settings of study and how those affect the results. (Institute for work and Health,2006) Nurses always learning something new skill from their past experiences. It increases their knowledge and skill, identify meaningful and relevant areas of study, interpret research finding, and giving a positive
