Islamic Extremism: Common Concern for Muslim and Western Publics

Methodological Appendix

About the 2005 Global Attitudes Survey

Results for the survey are based on telephone and face-to-face interviews conducted under the direction of Princeton Survey Research Associates International. All surveys are based on national samples except in China, India, Morocco 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.
