Tunisians Disaffected with Leaders as Conditions Worsen

Survey Methods

The survey in Tunisia is part of the larger cross-national Spring 2013 Pew Global Attitudes survey conducted under the direction of Princeton Survey Research Associates International.

Results for the survey in Tunisia are based on 1,000 face-to-face interviews conducted
March 4 to March 19, 2013. The survey is representative of the country’s adult population. It uses a multi-stage cluster sample design stratified by governorates and urbanity. All interviews were conducted in Tunisian Arabic.

The margin of sampling error is ±4.0 percentage points. 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.
