Once research questions and objectives are designed then sampling is needed. Selecting sampling is associated with objectives in order to answer the research problem. There are two types of sampling techniques namely probability which population is known and non-probability sampling in which the population is unknown (Saunders et al., 2009). According to this research, probability sampling is likely to be used, as this study needs an actual sample size, which can be calculated. In this project, selected participants will be Thai and British people.
