Results for the survey are based on face-to-face interviews conducted April 9 to April 30, 2010.  The survey in India is part of the larger 2010 Pew Global Attitudes survey conducted in 22 nations from April 7 to May 8, 2010, under the direction of Princeton Survey Research Associates International. (For more results from the 22-nation 2010 poll, see “Obama More Popular Abroad Than at Home, Global Image of U.S. Continues To Benefit,” released June 17, 2010.)

The table provides details about the survey’s methodology, including the margin of sampling error based on all interviews conducted in India.  For the results based on the full sample, 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.
