Survey Design

No two surveys are alike. Our statisticians work closely with clients to develop and implement survey designs that meet the requirements, challenges, and resource allocations for their specific research goals. These designs include plans for identifying potential survey subjects, selecting an unbiased sample of these subjects, gaining their cooperation, collecting their responses to survey questions, and producing analysis-ready data representative of the targeted population while maintaining the confidentiality of all survey respondents.
