Saunders, Thornhill and Lewis (2012) mentioned that to choose a suitable sampling technique for each research depended on feasibility of data collection and sensibility in order to answer the research questions and the research objectives from the whole population. Furthermore, there are two major types of sampling technique that include probability sampling and non-probability sampling, of which each type can be divided to several categories. For this research, the appropriated and selected technique is the convenience sampling of non-probability sampling, as this technique is considered as a time and cost effective technique for this research. Moreover, convenience sampling seems to be simple to manage in comparison with others sampling techniques, as the researcher can use social networks, such as Facebook to be the main communication channel to post the questionnaire (Henning, 2010).
