  • 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,…

  • Longitudinal Design

    include the following. The study is based on Experimental design. The investigators seek to test the efficiency of nursing interventions. Groove, Burns & Gray (2013) state: The three essential elements of experimental research are (1) randomization; (2) researcher-controlled manipulation of the independent variable; and (3) researcher control of the experimental situation, including a control or comparison group. Groove et al. 10381-10382 (2013). This study incorporates those three criteria.…
