Quizplus · Accepted Answer

Scientific surveys with randomly selected respondents and multiple random survey instruments are the most reliable method for obtaining accurate information for academic political research as they have the highest level of control and vetting of respondents and survey instruments. Random-digit dialing can lead to bias as it only includes those with landlines or cell phones, while internet-based polling can suffer from self-selection bias and lack of respondent filtering. Well-designed exit polls can provide valuable information, but are limited to a specific location and time period.
