❓ Frequently Asked Questions
What is public opinion?
Public opinion is the collective attitudes and beliefs of a population about issues or topics, used to gauge support and guide government decisions.
What are the main survey methods used to measure public opinion?
Questionnaires and interviews (online, phone, or in person) and polls are common. Governments often use probability-based sampling to ensure representativeness.
What is sampling and why is it important in surveys?
Sampling selects a subset of people to study. Probability sampling (random or stratified) lets researchers generalize findings to the whole population and estimate precision.
What are common sources of error in surveys, and how can they be reduced?
Nonresponse, poorly worded questions, and measurement errors can bias results. Use careful questionnaire design, pretesting, random sampling, weighting, and trained interviewers.
What legal and ethical considerations govern public opinion surveys in government?
Surveys should protect respondent privacy, obtain consent when needed, ensure confidentiality, comply with data protection laws, and be transparent about methods and limitations.
