Sampling Choices
The first choice to make is the type of sampling. In this case, random sampling will be adopted in order to ensure that the data obtained from the sample population is truly representative of the overall study population. This also contributes in making the study valid. Following this is the sampling frame, which will incorporate the details of elements of the population in which the sample is being constructed (Pajares, 2007). Having made these choices, the sample size for the study has to be considered, so that the study is able to operate within the budget and timeline.
Sampling Concerns
While making the choices for sampling in the study, validity is an issue for consideration. This indicates the extent of results interpretation to provide solution to study questions and be used in other situations. This validity has to be both internal and external validity. Internal validity focuses on the ability of the results for the study to emerge from the variables measured, manipulated, or selected in the study, but not external sources while external validity focuses on the ability of results from the study to be used in generalization of other situations (Hani, 2009).
In addition, sampling should be representative. This aids in ensuring that the study collects credible data from the research being conducted. This indicates that in the sampling process the characteristics of the sample have to be outlined. Further, in case a sample is obtained out of convenience the limitations and rationale for this action have to be provided. Finally, it is essential to consider the procedures to follow in order to obtain consent, as well as confidentiality and anonymity from the sample population. This contributes towards ensuring that the study obtains reliable and accurate results.
