Convention, without being documented by an International Anti-Fouling System Certificate, a verification should be carried out to confirm that the anti-fouling system complies with the requirements of the Convention. This verification may be based on sampling and/or testing and/or reliable documentation, as deemed necessary based on experience gained and the existing circumstances. Documentation for verification could be, e.g., MSDSs (Material Safety Data Sheets), or similar, a declaration of compliance

are representative of the whole population at a lower cost than collecting the data for the whole population” (Saunders et al: 2009, pp 144). There are some difficulties of using this strategy which will be considered in the data collection. b) Sampling strategy: Due to the huge number of customers and the huge geographical business operation, the population will be divided into strata. Each stratum will be the departure country or the departure city for domestic journeys which will be a stratum

have the respondent’s e-mail address attached. It is important that the researcher emphasizes that the confidentiality of the respondent will be protected”. 7 V. Sampling 1. Definition of the target population According to Malhotra NK. (2010), “the target population should be defined in terms of elements, sampling units, extent and time”.  An element is “an object that possesses the information sought by the researcher”. In the research that will be carried out, the elements are first

steps that will take place and the order that they will take place. Sampling is the process of selecting a number of individuals for a study in such a way that the individuals represent the larger group from which they were selected. Random sampling is the process by which all individuals in the defined population have an equal and independent chance of being selected for the sample. Stratified Sampling is the process of selecting a sample in such a way that the sample represents
