Surveys

We have more than 30 years of experience in conducting public opinion polls, customer satisfaction studies, needs assessments, market research, and program evaluation surveys. Our expert survey methodologists can assist you in defining the objectives of your survey, identifying the study population, optimizing the sample design, selecting the best method for survey administration, creating and pre-testing the survey questionnaire, analyzing the data, and interpreting the results.

We administer surveys by mail, by phone, on the Internet, or in person. We also have extensive experience with combination or “mixed mode” designs involving two or more methods of administration. We field our surveys in accord with the best practices and latest findings from the survey research literature, designed to achieve representative responses and unbiased results.

Sampling

We advise clients on sampling procedures to yield statistically reliable estimates of the characteristics, behaviors, attitudes, and beliefs of the population of interest. We can develop and implement an appropriate sampling strategy tailored to the specific research question, whether by random digit dialing, address-based sampling, stratification, clustering, or other more complex designs.
