Many questionnaires are made up of a series of different questions that use the same response categories (for example: strongly agree, agree, neither, disagree, strongly disagree). Some designs will have different groups of respondents answer alternate versions of the questionnaire that present the questions in different orders and reverse the orientation of the endpoints of the scale (for example: agree on the right and disagree on the left).

Some designs will have different groups of respondents answer alternate versions of the questionnaire that present the questions in different orders and reverse the orientation of the endpoints of the scale (for example: agree on the right and disagree on the left).
