• ## Nonprobability Sampling

Throughout scientific studies, researchers utilize sampling and conduct research that identifies probability and nonprobability, reliability, and validity of research. Also, scientists utilize telephone surveys, online surveys, focus groups, and surveys via websites when collecting data for research and need to be aware of the advantages and disadvantages of each of them. Sampling is the process of selecting a small part of a population for inspection and utilizing that smaller part of information to represent a larger population. It may be impossible for scientists to determine the characteristics of a vast population; therefore, the purpose and fundaments of sampling is to help scientists examine the characteristics of a larger population in a smaller way. Because information is taken from cautiously drawn samples within a smaller group, another fundament of sampling is receiving results that are more accurate than they would be from a larger group (Monette, Sullivan, & DeJong, 2011, p.135). Two methods used in research are probability and nonprobability sampling. Probability sampling such as simple random sampling (SRS), guarantees that all scientific components have an equal chance of being included in the sample (Monette et al., 2011, p.139). For example,…

more accurate our final results will be. Since our main sampling method uses the convenience approach, the majority of our sample will be UFV students. Our working population, the UFV students, represent the multicultural aspect of our target population well.

The safest way to ensure that it is representative is to use a random selection procedure. You can also use a stratified random sampling procedure, to make sure that you have proportional representation of population subgroups” (Hopkins, 2000). The flowing is the type that I will fit my research…

Apparently, McMahon Group’s sampling method…
