Publics of Asian Powers Hold Negative Views of One Another

Methodological Appendix

Results for the survey are based on telephone and face-to-face interviews conducted under the direction of Princeton Survey Research Associates International, which manages the fieldwork conducted by local research organizations in each country. All surveys are based on national samples except in China, India, and Pakistan, where the sample was disproportionately or exclusively urban.

The table below shows the margin of sampling error based on all interviews conducted in that country. For results based on the full sample in a given country, one can say with 95% confidence that the error attributable to sampling and other random effects is plus or minus the margin of error. In addition to sampling error, one should bear in mind that question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of opinion polls.
