One of the most significant issues investigators have to consider when designing a project concerns the type and number of the respondents who will be included in the study. A number of very important questions have to be answered, such as: Will the whole population or a sample be studied? If sampling is preferred, which sampling procedure is most suitable? How large should the sample be? Is there a sampling frame required? If yes, is one available? How representative should the sample be? How will possible problems, errors, distortions be prevented? What kind of administrative arrangements are required for the frictionless completion of these sampling procedures? Are the required time, funds and staffing available and, if so, how can they be rationally employed? How is non-response going to be dealt with in the study? Are there any issues of ethics and objectivity to be considered at this stage, and how will such requirements be met?
