Abstract
The precision of a survey depends largely on how the data is collected. Random sampling and face-to-face interviews, have been regarded as the best method to collect attitudinal data. Rapid changes in social environment of recent years have made it increasingly difficult to conduct face-to-face interviews of randomly selected respondents. At the same time, there is increasing need to obtain results quickly. As a result, other methods of conducting survey have emerged. This special issue contains articles on various survey methods used in media polls and academic research, focusing on survey methods(sampling methods and how the responses are obtained)and the precision of surveys(representativeness of the sample, valid response rates, and the characteristics of respondents).
