A major strategy of improving data saturation is making sure the recruited units for sampling have achieved saturation point (Patton, 2015). Likewise, this process means reaching a point in which all the relevant data of the research analysis have been obtained. For example, the recruited sample of patients with Alzheimer dementia have reached a basis for concluding or finalizing the research explanation that could lead to consequent data-wide.
Additionally, it is important to note the limitations that determine enough sample size. In some cases, researchers’ judgment and experiences, including appraising the quality of the composed data; type of research and the analytical approach may determine the limitations of sampling size (Sandelowski, 1995). A comparative study was used to describe how effective sampling strategies could be used for truck destination choice model (Park, Park, Kim, Kim & Park, 2013). Effective sampling strategies tell a lot about the quality of research study (Park et al., 2013).
