respondents supporting military action: only 43% said they favored removing Hussein under those circumstances. For more information on question wording experiments we have conducted see Question wording . We also have different forms of the questionnaire so we can ask more questions than we would otherwise be able to ask. If we determine that half of the sample will include enough interviews for a reliable estimate, we will often ask some questions of only half of the sample. That allows us to include more questions on the survey without burdening any individual respondent with a longer interview.
