Sample interview questions: How do you address potential biases related to nonrandom sampling in public opinion surveys?
Sample answer:
Addressing Potential Biases Related to Nonrandom Sampling in Public Opinion Surveys
- Stratified sampling: Divide the population into subgroups based on relevant characteristics (e.g., age, race, gender) and randomly sample within each subgroup.
- Quota sampling: Determine the desired proportions of different characteristics in the sample and recruit participants to meet these quotas.
- Weighting: Adjust the results of a nonrandom sample to represent the true population distribution by applying weights based on known population characteristics.
- Increase sample size: Enlarging the sample size can mitigate the effects of biases, especially when using nonprobability sampling methods.
- Use multiple sampling methods: Combine different nonrandom sampling methods (e.g., stratified and quota sampling) to capture a more diverse range of the population.
- Conduct pilot studies: Test the effectivenes… Read full answer
